Summary:This paper illustrates the ability of Gaussian beam shooting techniques to accommodate large propagation problems in multipath contexts. Frame based decomposition of fields provides a flexible and efficient tool to perform beam launching. Channel transfer matrices are defined, which allow for a complete description of multidimensional channels through a limited number of coefficients. A beam re-expansion algorithm is proposed to address the problems of beam widening, and diffraction by objects with limited extension, through the conjoint use of wide/narrow frame windows.
