Abstract
This paper describes the application of joint time-frequency analysis (JTFA) to finite-difference time-domain (FDTD) simulations of several shielding structures. Several detailed examples are given that highlight the use and application of JTFA. Joint Time Frequency Analysis (JTFA) is a powerful tool that is used to post process waveforms obtained from time-domain numerical simulations. JFTA is applied directly to a numerically generated time-domain record, and useful parameters can be extracted using an efficient data processing sequence.
