Abstract

The condition number scaling for a conducting strip and resonant cavity for the transverse magnetic (TM) and transverse electric (TE) polarizations is given. Three sources of ill-conditioning are identified: increasing discretization density, surface wave self-coupling, and resonance. Changing to a second-kind integral equation eliminates the first two sources, but real resonances still cause ill-conditioning.
