How to reduce the cost of IC test has become the focus of the integrated circuit industry. This article proposes a method to improve the testing efficiency based on some dynamic parameters of ADCs and radio frequency chips. Aiming at the characteristic that the traditional sine wave test method can only test one frequency point at a time, this method can realize the test of multiple frequency points at a time, which reduces the chip test time and the test cost.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126463678","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}

Because these random phase gradients, the incidence waves are diffused, which results in RCS reduction. Importantly, under both linearly polarized (LP) and circularly polarized (CP) incident waves, these random phase gradients are always available on the metasurface, and they are not sensitive to the polarization state for either CP waves or LP waves. When the incident angle of LP and CP waves is increased, these random phase gradients are also available on the metasurface. Therefore, a true polarization-independence metasurface is realized for wideband and wide-angle RCS reduction. For both LP and CP incident wave, −10 dB RCS reduction bands are from 13.5GHz to 22 GHz. Simulation and experiment results all show this proposed metasurface has potential application for stealth technology.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133120654","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}

Since the integral featuring high-frequency oscillation and slow decay may lead to a time-consuming calculation process. With optimal approximation and global optimum characteristics that cannot be found in other feedforward neural networks, the RBF neural network is adopted in this paper to solve the dyadic Green function. By doing so, the efficiency of solving Dyadic Green's functions can be enhanced thanks to its simple structure and fast training speed.
