Abstract

By extending frequency-domain (FD) asymptotic solutions, we develop novel time-domain (TD) asymptotic-numerical solutions (TD-ANSs), which are new reference solutions on engineering applications, for a transient scattered electric field from a two-dimensional coated cylinder covered with a thick dielectric medium. The TD-ANSs newly include the multiple reflection effect passing through the coating medium as compared with a conventional TD-ANS. The TD-ANSs are highly accurate and are useful because they can extract and interpret each pulse wave element from a response waveform including the multiple reflection effect even when pulse wave elements overlap mutually. The validity and usefulness of the TD-ANSs are confirmed by comparing with a reference solution.
