Low‐frequency asymptotics for dissipative Maxwell's equations in bounded domains

摘要

AbstractConsider a bounded domain Ω surrounded by a perfect conductor and containing a conducting cavityD. The behaviour of the solutions of the time harmonic Maxwell problem as frequency tends to 0 is analysed in this situation. Necessary and sufficient conditions on the excitations are given which guarantee the existence of a limit. This limit turns out to be the solution of some static problem
