Abstract

The indoor propagation simulation of hybrid methods are employed. Usually for microwave band the hybrid method is based on ray tracing. In this case for numerical field calculation in regions with a small obstacles is selected finite element method (FEM). This paper explains solution method for two - dimensional FEM region with a boundary integral mesh truncating. Solving the system of FEM equations and boundary conditions, the field and its normal derivatives on boundary of region are determined. This solution gives orientation and field intensity for secondary source. Ill 4, bibl. 5 (in English; summaries in Lithuanian, English, Russian).
