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