Analysis of Non-Linearly Loaded Antennas and Scatterers

A very efficient numerical technique for the analysis of non-line arly loaded antennas and scatterers is proposed. It is based on a generalization of the piecewise harmonic balance method, which overcomes the need to examine the complete transient development in the time domain. The algorithm enables the analysis of multiport nonlinearities expressed even in implicit form and appears to be extremely useful even with strong nonlinearities. This approach is found to be highly recommended for applications which only require the steady-state responses such as co-operative targets and environmental measurement techniques. An example of application is given.
