Electric Field Suppression Strategy for RCS Reduction of Curved Target at TM Polarization

An electric field suppression strategy is proposed in this paper to address the issues inherent in the RCS reduction design of curved targets at TM polarization. Firstly, the equivalent models of a PEC cylinder with opaque impedance surface or loaded with a lossy dielectric are constructed and been analyzed through eigenfunction expansion. Secondly, the impacts of opaque impedance surface and lossy dielectric on the electric field distribution and RCS are investigated through simulation and test. Finally, the specific implementation strategy of electric field suppression was put forward, with the aim to provide effective and intuitive guidance for the RCS reduction design of curved target at TM polarization.
