TLDR
In this article, the electromagnetic field propagates in a dielectric-filled transverse electromagnetic waveguide, and at least one slice of an electro-optic material is disposed in the DME for modulation by the incident electromagnetic field.Abstract:
A method of and apparatus for modulating an optical carrier by an incident electromagnetic field. The electromagnetic field propagates in a dielectric-filled transverse electromagnetic waveguide, At least one slice of an electro-optic material is disposed in the dielectric-filled transverse electromagnetic waveguide, the electro-optic material in the dielectric-filled transverse electromagnetic waveguide having at least one optical waveguide therein which has at least a major portion thereof guiding light in a direction orthogonal with respect to a direction in which the dielectric-filled transverse electromagnetic waveguide guides the incident electromagnetic field. Light is caused to propagate in the at least one optical waveguide in the at least one slice of an electro-optic material in the dielectric-filled transverse electromagnetic waveguide for modulation by the incident electromagnetic field.read more

Method and apparatus for coupling an antenna to a device
Paul Shala Henry,Donald J. Barnickel,Farhad Barzegar,Robert Bennett,Irwin Gerszberg,Thomas M. Willis +5 more
TL;DR: In this paper, the authors describe a system that receives, by a feed point of a dielectric antenna, electromagnetic waves from a core coupled to the feed point without an electrical return path, and radiates a wireless signal responsive to the electromagnetic waves being received at the aperture.

Wide-Angle Metal-Plate Optics
TL;DR: In this article, the design equations for constrained metal-plate lenses are derived and the scanning aberrations are investigated by means of a power series expansion of the phase error, which may be eliminated by the proper choice of lens thickness.
