Paper Abstract

Applying scalar diffraction theory in the near field of weak phase objects, a simple relationship with the diffracted field behind an aperture of identical form in a black screen is observed which allows a formulation of a modified Babinet principle for complementary weak phase objects. Its validity is demonstrated in the near field behind complementary dielectric objects using a modified Mach-Zehnder interferometer for 3 cm microwaves.
