The Antenna Current Green's Function as an Alternative Method to Conventional Full-Wave Analysis Solvers: An Outline

The paper presents an overview on a general method to compute the response of arbitrary electromagnetic systems to generic illumination field (i.e., not necessarily plane waves or wave port fields) without the need to re-mesh the physical layout for different excitation fields. The basic idea is similar to the transfer function in system theory were a special solution of the problem (the Green's function or the impulse response) is computed only once and then used to predict the electromagnetic behaviour of the device under varying environmental circumstances.
