Аннотация:The problem of diffraction by a thin cone
is considered. The parabolic equation of diffraction
theory is used as the governing equation. Authors
introduce the method of a boundary integral equation
for the parabolic equation. The integral equation
is derived by applying the Green’s theorem.
The kernel of the equation has a difference form,so
the equation can be solved analytically using Fourier
transform. As the result,some known formulae can
be re-derived. Also,the integral equation can be
solved numerically by iterations.
