Advanced Antenna Design
Home About the Center Sponsors Facilities Focus Research

GOAL: Design high performance GRIM (Gradient Index MetaFerrite) antennas exploiting the gradient properties, high index, and vacuum match of MetaFerrites.

Motivation: Enable compact antenna system with good match to vacuum.


Gradient Index MetaFerrite (GRIM) flat thin lens or reflector can replace deep dish antenna


Gradient Index Metaferrite Lens (GRIM)
(max index n=60)

Normal Dielectric Gradient Index Lens (GRIN)
(max index n=3)

 

High variable refractive index with simultaneous control of permittivity and permeability allows practical realization of vacuum matched thin flat gradient index antennas and lenses.
