开孔屏蔽腔内传输线负载所受电磁干扰的解析算法
Analytic formulation for load response of transmission line enclosed in enclosure with apertures
摘要
Abstract
Based on electromagnetic topology and equivalent circuit method,this paper presents an analytic method for the fast prediction of the load response of the transmission line in an enclosure with apertures,irradiated by an external plane wave.In the method,the whole electromagnetic coupling problem is firstly decomposed into two relatively simple sub problems:a)the ex-ternal plane wave irradiates an empty enclosure with apertures and generates interior coupling EM field,and b)the coupling field irradiates the isolated transmission line and generates the load response.Then,the coupling field is computed by equivalent circuit method,and the load response of the transmission line is computed by BLT equation.The validity of the analytic method is veri-fied by CST simulation tool.The results show that the analytic method can calculate the load response of the transmission line fast and efficiently,and costs much fewer computing resources compared with numerical methods.In addition,the analytic method offers designers feasibility to study influence parameters on the load response of the transmission line,while it is difficult with nu-merical methods.关键词
