Imaging using millimeter waves (mmWs) has many advantages and applications in the
defense, security, and aviation markets. All terrestrial bodies emit mmW radiation, and these …

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 …

The EU FP7 project CONSORTIS (Concealed Object Stand-Off Real-Time Imaging for
Security) is develo** a demonstrator system for next generation airport security screening …

In this paper, we present a flat transmission-type focusing metasurface for the near-field
passive millimeter-wave (PMMW) imaging systems. Considering the non-uniform wavefront …

A wide field of view (FOV) inversely magnified dual-lens system for submillimeter
wavelength imagers is presented in this paper. The antenna is designed for near-field …

In this paper, the practical tradeoffs for designing submillimeter wavelength imagers based
on optomechanical systems combined with focal plane arrays (FPAs) are presented. The …

Wide-angle, high-efficiency, wide-band, and ultra-compact focusing blocks are crucial for
implementation and future evolution of passive millimeter-wave focal plane array imaging …

There is ongoing worldwide interest in finding solutions to enhance the security of civilians
at airports, borders and high risk public areas in ways which are safe, ethical and …

We show the diffuse and specular reflection images of defective foams placed on iron plates,
which are obtained by a bifocal active imaging system at 0.22 THz. Foam materials studied …

Free-form two-mirror antenna for millimeter wave imaging has been modeled using a
proprietary software for optical systems design PODIL. Optimization procedure is based on …
