Design and focussing characteristics of a microwave paraboloidal zone plate
Abstract
On the basis of a simplified ray theory, the design and the focusing properties of a microwave paraboloidal zone plate with a spherical wavefront incident on its convex side is presented. Numerical values for the variation of relative field amplitude with axial distance and also the variation of field amplitude with frequency have been computed. The results are discussed.
