The applicable scopes of the Nakagami distribution and the Rayleigh distribution are analyzed based on the observations of the amplitude scintillations recorded in the low-latitude of China. It’ concluded that the scintillation amplitude is more likely to obey the Rayleigh distribution when the S4 index is greater than 0.7. By the variation of “m-coefficient”, the Nakagami distribution could represent the Rayleigh distribution. Therefore, a new relationship between the S4 index and the “m-coefficient” of the Nakagami distribution is put forward, which can much better describe the fading distribution of amplitude scintillations in the whole range of S4 and also is simple enough for the engineering application.","PeriodicalId":287986,"journal":{"name":"2021 13th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117213598","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}

Finally, all phases are subtracted in pairs to obtain the phase-difference of any two units. If two units have phase difference range of (180° ± 37°) at the widest continuous frequency band, the two metasurfaces composed of the two units will have the wider 10dB reduction bandwidth than any other simulated unit.
