Electromagnetic propagation in structures and buildings—research at the University of Auckland

An outline of research into the electromagnetic characterisation of propagation in building structures being undertaken at the University of Auckland is presented. Improved system performance is the key driver, and quantifying this requires a good understanding of radiowave propagation - in particular co-channel interference. Results from various techniques (including the Green´s function/Method of Moments and FDTD) are presented and are shown to be capable of isolating the key propagation mechanisms responsible for interference. This knowledge is being used to formulate simple yet accurate propagation models for use in system design. The use of frequency selective surfaces to control interference is also described and shown to be a feasible approach.
