Abstract 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. Key Words: Wall loss, conductor
loss, surface impedance, microwave heating cavity, finite elements |
