Abstract :
A hybrid method to study the problem of wave propagation and scattering in an indoor environment in the presence of inhomogeneous periodic walls is proposed. The method makes it possible to accurately study the effects of inhomogeneous walls in a 3D environment and was validated withh both theory and measurement. Contrary to full-wave analysis, it is capable of handling large 3D structures.
