Human-made or natural electromagnetic interference has a large effect on electronics. Both the couple of signal cable and the bit error rate during highspeed communication affects the reliability of equipment. Thus, electronic equipment with these problems is bad for the process of industrial production. Electromagnetic shielding is a good method to improve the radiated susceptibility of electronic equipment. The material of the chassis, the structure of chassis, and the thickness of the chassis wall affect the shielding effectiveness of chassis. Thus, in order to investigate the effect of microwave absorption material on the shielding effectiveness of chassis. This article is based on the material of the chassis, combing the simulation of High Frequency Structure Simulation (HFSS) software, to study the effect of MXene-based microwave absorption material on the shielding effectiveness. The simulation results indicate that chassis optimized by MXene-based materials has a better shielding effectiveness. When the thickness of the microwave absorption material is 0.6 mm, it shows a good shielding effectiveness.

Visibility is a complex assessment process, but our current understanding of how the eye receives and processes light and how well the eye can distinguish objects in different lighting levels and distances are low. The current approach for calculating outdoor lighting level requirements is complicated and limited to illuminance and luminance measurements and does not allow designers to evaluate visibility. This paper aims to develop a simple outdoor lighting visibility calculation using the photons per second. This novel calculation method is applied to the candlelight's visibility distance and the milky way’s Vega star visibility to validate the calculation approach. This paper will help researchers, scientists, engineers, consultants, architects, lighting designers, and government agencies seeking to improve outdoor lighting for safety, health, well-being, and quality of life in the built environment.","PeriodicalId":194720,"journal":{"name":"SCIREA Journal of Physics","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115829998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
