In this SIE, the whole target is divided into several different sub-regions by using the idea of domain decomposition (DD). Then, on the basis of the current coefficient matrix obtained by MoM, this SIE method can calculate the contribution value generated by electromagnetic flows on each component region from the sub-region by marking and partitioning the target. Moreover, two technologies are further adopted to enhance the efficiency and flexibility of this SIE method. One is that curved triangular elements and higher order hierarchical vector (HOHV) basis functions are applied, which can remarkably reduce the unknown amount of the conventional SIE. The other is that a DD method is adopted to employ a discontinuous Galerkin (DG) approach to glue conformal/ nonconformal surface grids between adjacent subdomains. It is obvious that this HO-SIE based on DDM can further increase the flexibility of geometrical modeling and accelerate the convergence of the HO-SIE for electrically large and multiscale metallic targets. Finally, two numerical results are given to demonstrate the validity of this method.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115113067","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}

The circuit is mainly composed of a transmission line coupled with three groups of symmetrically coupled microstrip lines. In order to increase the absolute value of the negative group delay (NGD) at each frequency point, Genetic Algorithm is chosen to optimize the NGDC, and the NGD result has been significantly improved. Through physical processing and testing, the experimental results are in good agreement with the simulation results, which proves the quad-band NGD characteristics of the circuit and the feasibility of GA to optimize NGDC. Experimental results show that at 6.74GHz, 7.13GHz, 9.97GHz and 11.20GHz, the negative group delay values are -3.8ns, -2.7ns, -3.8ns and -5.4ns, respectively.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125060625","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}

In this array, the longitudinal slot etched on the broad sidewall of the SRWG is employed for vertical polarization (VP) radiation, while the inclined slot cut in the narrow wall of the RWG is employed for horizontal polarization (HP) radiation. From the simulated results, the bandwidth of the designed antenna for voltage standing wave ratio (VSWR) < 1.5 is 0.8GHz at the center frequency of 9.4 GHz. The realized gain at 9.4 GHz is 31dBi with antenna efficiencies better than 83%. The side-lobe level is controlled lower than -31dB over the entire bandwidth. The beam width is 1.6 degrees and the beam direction is 4.5 degrees at 9.4 GHz. The realized gain, beam width, beam pointing and side-lobe of the two polarization modes are almost the same at 9.0GHz, 9.4 GHz and 9.8 GHz.

Various de-embedding techniques have been proposed to expose the real electrical behaviors of a DUT, e.g., the traditional thru-reflect-line and short-open-load-thru algorithms, where the T-matrix and its inverse form are adopted in the mathematical process. In the fields of radiofrequency and electromagnetic compatibility, a DUT may have three coupled ports, and the symmetry in the associated S-matrix breaks down, because the numbers of entry and exist ports are not equal, which results in a non-square T-matrix based upon the definitions. Given that the inverse expression of a non-square matrix does not exist, the conventional de-embedding methods are not applicable for a coupled three-port network. In this paper, a de-embedding algorithm which is feasible for coupled three-port devices is proposed and verified through the measurement-based studies. The de-embedding technique may also be applied on devices with more than three ports.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129716985","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}
