Abstract
An apparatus having a reduced reflection from its surface includes a dielectric material and a capacitive circuit analog sheet buried within the dielectric material and configured to produce a reflection that adds out of phase with a reflection from an incident side of the dielectric material. The capacitive circuit analog sheet comprises conductive patches configured to have high impedance for transverse magnetic (TM) polarization.
Claims10
An apparatus having a reduced reflection from its surface, said apparatus comprising:
- a dielectric material;
- a first anisotropic capacitive circuit analog sheet buried within the dielectric material and configured to produce a first reflection that adds out of phase with a reflection from an incident side of the dielectric material;
- and
- a second anisotropic capacitive circuit analog sheet buried within the dielectric material and configured to produce a second reflection that adds out of phase with the reflection from the incident side of the dielectric material, wherein at least one of the first anisotropic capacitive circuit analog sheet and the second anisotropic capacitive circuit analog sheet comprises conductive patches configured to have high impedance for transverse magnetic (TM) polarization.
