The response of antennas with nonlinear loads is investigated. In this contribution we present a method capable to perform simulations on antennas with multiple nonlinear loads that are less time and memory consuming than traditional proceedings. Moreover, these methods also contribute to a better understanding of observed effects. This is shown using an antenna with two nonlinear loads. A deep insight on how nonlinear loads affect the reception behavior of an antenna will be provided.

In this contribution the effects of repetitive pulse excitations on linearly and nonlinearly loaded antennas are studied on the basis of equivalent circuit models. This is important to understand in the context of Electromagnetic Compatibility possible nonlinear effects which often are not included in the analysis. It is found that a surprisingly large capacitive effect can be produced which has no counterpart in the linear case and is accompanied by the storage of unwanted electric energy.

In this article the modeling of electromagnetic field coupling to nonlinear devices is studied. This is of benefit in the context of Electromagnetic Compatibility where the interaction between sensitive electronics within complex systems and electromagnetic interference is investigated.

A numerical method is presented which is capable to compute the electromagnetic fields created by the current of a spatially extended lightning channel. The coupling of these fields into simple models of aircraft fuselages is investigated, where the electric material parameters of the fuselages correspond to those of realistic layered carbon fiber composite.
