A simple and low-cost solution to reduce the height and weight of extended hemispherical
lenses is proposed based on the introduction of a cylindrical air cavity above the primary …

Large format focal plane arrays (FPAs) of dielectric lenses are promising candidates for wide
field-of-view submillimeter imagers. In this work, we optimize the scanning gain of such …

This communication provides guidelines for the design of two-shell radially symmetric
dielectric lenses with collimating capabilities compatible with those of the classical Luneburg …

Quasi-optical imaging systems require low blurring effect and large depth of focus (DOF) to
get an acceptable sharpness of the image. To reduce aberration-limited blurring, the …

Focal-plane reflector feeds with shared aperture are a promising solution for the increasing
number of beams required in the Ka-band satellite services. Stringent manufacturing …
