Analysis of Metallic Wire with Variable Radius Using Surface Integral Equation
Analysis of metallic wire is a classical topic in Computational Electromagnetic (CEM).It is very important for wire antennas design and RCS reduction research of metallic wires.Moment method (MOM) based on electric field integral equation (EFIE) is a very effective way to solve metallic wires by meshing them with discrete points.However,traditional MOM mainly focuses on the metallic wires with constant radius.In this paper,higher order MOM is discussed and is used in analysis of metallic wires with variable radius.In order to obtain a higher accuracy than that with MOM based on RWG basis function,higher order polynomial expansion is adopted to approximate the current on the wire.This method can reduce the unknowns of models and make the simulation result more convincing.In order to verify the novel performance of higher-order basis function on the analysis of metallic wire with variable radius,two models are tested with the codes based on this method.In addition,they are also solved by other commercial code to test the accuracy of higher order basis function.Very good consistency of the data curves proves the accuracy and high efficiency of this method.
