Abstract. A problem of synthesis of
two dimensional mirror shape formed by a reflected surface with a sufficient
dependence of reflection coefficient on angle of incidence is considered. A
phase of the reflected field is determined in frame of model of the reflected
surface as an impedance wall with non-local boundary conditions. The phase then
is used for synthesis of mirror shape that provides the required transformation
of wave field. A synthesis of mirror that transforms point source into plane
wave is considered as an example.
Keywords: planar mirror, mirror
shape synthesis, non-local impedance boundary conditions.
