In this article, the frequency‐dependent finite‐difference time‐domain (FD) 2 ‐TD technique is used to analyze a coaxial‐line excited cylindrical cavity loaded with an electrically lossy dielectric, modeled by a first‐order Debye expression. Results obtained for the reflected voltage in the coaxial line are Fourier transformed to yield the reflection coefficient Γ and input admittance at the coaxial aperture. Experimental measurements for Γ show good agreement with predicted (FD) 2 ‐TD results.
