This paper presents an innovative method for the design of planar lens inside parallel waveguide using Fakir's bed of nails substrate (FB) [1]. The FB is used to modulate the surface impedance on a boundary of the waveguide in order to obtain the desired refraction index for the guided wave. The method is general and can be used to design any kind of planar lens.

Abstract
This paper presents an innovative method for the design of planar lens inside parallel waveguide using Fakir's bed of nails substrate (FB) [1]. The FB is used to modulate the surface impedance on a boundary of the waveguide in order to obtain the desired refraction index for the guided wave. The method is general and can be used to design any kind of planar lens.
