DIFFRACTION FIELD BEHAVIOR NEAR THE EDGES OF A SLOT AND STRIP

By V. M. Serdyuk

Full Article PDF (2,590 KB)

Abstract:
The diffraction field asymptotics on the edges of a slot in the plane conducting screen and of a complementary strip is considered using the exact solutions of corresponding stationary diffraction problems, which have been derived before on the bases of the slot (strip) field expansions into discrete Fourier series. It is shown that as nearing the slot (strip) edges, the fields decrease or increase indefinitely in magnitude by the power law with an exponent of modulus less than unity, so the given exact diffraction solutions yield finite value of electromagnetic energy density in any point of space.
