BACKSCATTERING FROM SOFT-HARD TRIANGULAR CYLINDER: PRIMARY PTD APPROXIMATION

Özet

High-frequency diffraction from isosceles triangular cylinders with two facessoft and one face hard is investigated for backscattering case and novel first-order physicaltheory of diffraction asymptotics are derived. Only primary edge waves are taken intoaccount. It is shown that, by changing the apex angle of the cylinder, PTD results ofthe soft-hard triangular cylinder agree-well with those of the PTD results of Soft-Hard Strip.
