The existing harmonic cancellation methods include the use of filter banks for harmonic cancellation and digital harmonic cancellation, but these methods will either increase additional hardware resources or only work for harmonic cancellation, neglecting intermodulation. Based on the analysis of the Volterra series, the harmonic cancellation memory polynomial (HCMP) model is proposed. Experimental results show that at the same model complexity, compared with GMP model, the HCMP model has improved the harmonic cancellation ability at different frequency points, in which the second harmonic improved by about 8 dB and the third harmonic improved by more than 12 dB. Meanwhile, the IMD5 and IMD7 cancellation performance of the HCMP model is about 1.6 and 4 dB better than that of the GMP model.","PeriodicalId":13130,"journal":{"name":"IEEE Microwave and Wireless Components Letters","volume":"32 1","pages":"1223-1226"},"PeriodicalIF":3.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46692670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, the existing Babinet principle requests homogenized substrate to cover complementary metallic elements. In order to break this restriction, the concept of effective relative permittivity is introduced to keep the original boundary condition unchanged. Further, the extended Babinet principle is expressed as a mathematical equation including vector fields of complementary metallic elements on the substrate interface. Especially, the proposed theory is related to the accuracy of the effective permittivity. In order to verify the proposed theory, the extended Babinet principle is applied to complementary metasurfaces with the approximate effective permittivity. Great consistence exists between theoretical and simulated results. Thus, the extended Babinet principle not only provides a theoretical approach to analyze complementary metallic elements on the substrate interface but also greatly enriches the physical connotation of existing Babinet principle.","PeriodicalId":13130,"journal":{"name":"IEEE Microwave and Wireless Components Letters","volume":"32 1","pages":"1151-1154"},"PeriodicalIF":3.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48444277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
