A NEW ANALYTICAL METHOD OF SOLVING

2-D DIFFRACTION PROBLEMS

Michael V. Vesnik,
Institute of Radioengineering and Electronics of Russian Academy of Sciences

A new method of solving 2-D diffraction boundary problems for perfectly conducting half-infinite scatterers is presented. The method is based on constructing a universal integral representation of the diffracted wave with use of the theory of conformal transformations. This diffraction wave in integral form being summarized with geometrical optics components of incident and reflected waves represents a solution of Helmholt's equation boundary problem. A rigorous solution for half-infinite scatterers with polygonal envelope is received. The asymptotic of the integral representation is constructed in a compact form, convenient for further applications.
