It is shown that the image contrast in the air when using a microscope based on dielectric
microparticles with a size of the order of wavelength can be significantly enhanced with the …

We report on resolution enhancement of sub-terahertz (THz) images by using the terajet
effect. A mesoscale cuboid dielectric particle, used to establish the terajet, was placed in …

In this paper, we propose a computational approach for description of radiation transfer in a
quasi-ordered medium and study the impact of scattering on electromagnetic wave …

Metamaterial apertures-based computation imaging system enables interrogating the scene
information with frequency-diverse complex radiation fields, reducing the complicated active …

Due to the flexibility in system design and small form factors, frequency-diverse imaging
regime gained popularity in recent millimeter-wave (MMW) computational imaging (CI) …

A millimeter-wave (mmW) range enhancement imaging technique for multistatic planar
