The scholarly article represents the results of the experiment conducted by Zhi Hao Jiang and the group of researchers from the Pennsylvania State University who fabricated plasmonic metasurface-based nanostructures for using them to change certain properties of light. The purpose of the research was to fabricate the specific two-dimensional metasurfaces that could alter the properties of light with the focus on the polarization transformation (Jiang et al. 2).

The researchers analyzed the limitations and drawbacks of different types of waveplates to achieve the desired optical effect and polarization conversion, and they constructed the plasmonic metasurface-based nanostructures that combined all the desired properties. Much attention was paid to the qualities of broadband waveplates and wide-angle wave plates for polarization conversion.
The next stage of the research was the experiment during which the researchers found that the fabricated waveplates made of subwavelength nanoresonator arrays converted the polarized light, and the other optical functions were observed. The experiment demonstrated that the researchers fabricated the high-quality wide-angle reflective metasurface-based waveplates that are characterized by the high polarization conversion capacity (Jiang et al. 5). As a result, these waveplates can be actively used in optical characterization, communication technologies, and sensing.
The media article discussed the results of the primary experiment conducted by a team of electrical engineers working at the Pennsylvania State University. It is reported in the article that a unique metallic nanostructure was designed and tested to manipulate the light. Thus, the manipulation of the light became possible while using the specific system of resonators.
The authors of the article noted that such a nanostructure can be effectively used in optical characterization, sensing, and different communications, while referring to the comments of Zhi Hao Jiang, one of the researchers, on the advantages of polarization transformation. The authors of the article compared the new wave plates with the previously used ones and stated that the experiment demonstrated the increases in polarization conversion rates in more than 92% (“Two-Dimensional Metamaterial Surface Manipulates Light” par. 3).
The discussion of the qualities is supported with the opinion of Jeremy Bossard, the team member who did not perform as the author of the article, who pointed at the ability of the surface to provide the same reflection in spite of the angle. In conclusion, the authors of the media article accentuated the increased functionality of the nanostructured waveplate.
The scholarly article is divided into four large sections that are further divided into subsections. The first part of the article presents the introductory statements and the general discussion of the purpose of the research and the purpose of the article that is to demonstrate the results of the conducted experiment. The most important section in the article is Results that is divided into several subsections.
The researchers separately discuss the process of designing and the structure of fabricated waveplates; the desired optical effect produced by the used metasurface; the specific features of broadband and wide-angle waveplates; the simulation and experiment; and the demonstration of a fabricated waveplate with desired qualities. The next small section is Discussion that also presents the conclusions of the research. Such methods used in the research as simulation and experiment are described additionally, after the concluding section.
The media article is not properly structured and divided into sections. The only identified part of the article is Summary placed before the introductory part. However, the information presented to readers can be discussed as structured according to the paragraphs. The first introductory paragraph summarizes the nature of the research experiment and its benefits. The second paragraph presents the description of the research given by the author of the experiment. The third paragraph discusses findings. The fourth paragraph presents the expert opinion on the research. The next paragraph discusses the advantages of the device, and the final paragraph names the other authors of the research.
Thus, the structure of two articles differs significantly.
In the media article, the results of the experiment are discussed rather generally, with the focus on the outcomes of using the device fabricated by the researchers and on the application of the experiment’s findings. However, to support the discussion of the conducted experiment’s importance, the authors of the media article provide actual numbers to support the idea that the fabricated waveplates can achieve the measured polarization conversion higher than previously researched waveplates, such as optical, conventional, and thin waveplates.
Thus, the nanofabricated waveplates can demonstrate the increases in polarization conversion by more than 92% (“Two-Dimensional Metamaterial Surface Manipulates Light” par. 3). In addition, the authors supported the general discussion of the results with the help of one picture that demonstrates how the circularly polarized light can be converted into a linearly polarized wave as a result of using the fabricated waveplate.
Comparison of Conclusions
While concluding on the results of the research, the authors of the article focused on stating that their approach can be discussed as effective to produce metasurface-based waveplates that can change the polarization qualities of light. The researchers also accentuated how the waveplates actually work depending on the qualities of the nanorod array of resonators. Finally, the researchers stressed on the actual results of the experiment stating that the fabricated waveplates demonstrate the higher ratios in polarization transformation than other types of waveplates.
If the authors of the research article focused on the general review of the experiment’s results with the focus on the general features of the metasurface-based waveplates, the authors of the media article chose to conclude with accentuating the increased functionality associated with using new metasurface-based waveplates. The authors emphasized that the fabricated device is characterized by the wide field of view, and it can be discussed as the first unique optical device of such type.

The media article does not criticize the data or conclusions. The scholarly article does not criticize the conclusions, but provides statements regarding the areas for the further research.
It is important to note that the media article fails to mention the perspectives for the further research identified by the researchers in their paper. Jiang and the group of researchers focused on the necessity to extend the general design approach of the article in order to focus on studying nanostructured optical components (Jiang et al. 6).
Referring to the title of the media article, “Two-Dimensional Metamaterial Surface Manipulates Light”, it is possible to state that it accurately reflects the content of the media article that in simple terms discusses the results of the experiments conducted by Jiang and the group of researchers. However, this title cannot be discussed as accurate while discussing the content of the original research article. The problem is in the fact that the title of the media article lacks details identifying the qualities of the waveplates and the changed terms are presented in the tile of the media article in order to discuss the experiment’s nature and results.
The exercise can be discussed as effective to give insights into how scientific research and experiments can be done and reported in both the media and scholarly articles. It is important to pay attention to the fact that media articles are appropriate to discuss the results of the research in simple terms in order to make the findings understandable for the audience. Furthermore, the media article can present the information like the expert opinion or the post-discussion of the results by the researcher that were not previously provided in the research article. In its turn, the structure of scholarly article is important to be explored in order to understand how the results in the area of physics of light can be reported.
