RESUMO
A study is made into the numerical modeling of wall losses for a microwave heating application. It makes use of a surface integral term for both a frequency and time domain finite edge element formulation in order to model the wall impedance of the enclosed microwave cavity. The paper describes how the surface element matrix of the complex wall impedance is combined with the matrix formulation. The results are checked against analytical expressions for a single mode resonant cavity. An analysis on the effect of lossy walls is provided using four low-loss material insertions over a range of surface conductivities.
