Iterative solution of a nonlinear antenna problem inside a high-quality resonating chamber

In the EMC community it is known that the inclusion of nonlinear electric and electronic components inside electromagnetic resonators can lead to unwanted and unexpected resonance effects. Also the inclusion of nonlinear electric and electronic components in EMC analysis is known to be a mathematically challenging task which often is formulated in terms of a network problem. In this context, this contribution outlines for the canonical example of a nonlinearly loaded antenna inside a resonator an iterative solution procedure which allows to determine the antenna current as basic solution variable.
