A compact narrow-band BPF can be obtained by combining the proposed SSPP structure with half-mode substrate integrated waveguide (HMSIW).

In this paper, the parasitic parameters introduced by solder are found to consist of two parts by employing commercial full-wave simulation software. One is the parasitic capacitor between two pieces of solder, another is the parasitic capacitor between solder and ground plane.

In this paper, based on the field-line coupling principle, the vehicle cabin and motor drive system cable models are established using CST software. The induced currents and voltages on various cables of the motor drive system and the electromagnetic responses in the cabin and on the cabin surface under HEMP irradiation are obtained by simulation. The results show that unshielded cables are coupled to high voltage and current; the installation position of the resolver at the motor shaft end and the low-voltage port of the motor controller induce a strong electric field; the intensity of the electric field coupled to the vicinity of components with metal shells is relatively large and the surface current density coupled to the area with a smaller radius of curvature and the edge of the body structure is high. Therefore, these positions need to be designed for electromagnetic protection.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"101 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":"132299086","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}
