ABSTRACT:
A horn antenna includes a conducting horn having an inner wall and a first dielectric layer lining the inner wall of the conducting horn. The first dielectric layer includes a metamaterial having a relative dielectric constant of greater than 0 and less than 1. The horn antenna may further include a dielectric core abutting at least a portion of the first dielectric layer. In one aspect, the dielectric core includes a fluid. A waveguide including a metamaterial is also disclosed.
