A causality preserving interpretation of the electromagnetic (EM) leaky-wave (LW) propagation in space and time is proposed for the first time. The Cagniard-deHoop (CdH) joint transform technique is applied for elucidating the relation between time-domain (TD) head waves (HWs), body waves (BWs), Cherenkov wave effects, and LWs. It is...

The development of a low focal number and low-mass lens antenna is presented that enables terahertz spectroscopy applications on ultracompact platforms. The antenna operates efficiently over a 20% fractional bandwidth, from 450 to 550 GHz, with a gain of 50 dBi at 500 GHz. The antenna consists of a hyperbolic silicon lens that is placed in a...

Low relative permittivity plastic elliptical lenses in combination with integrated focal plane arrays are a promising solution to be used in the future mm- and sub-mm-wave systems. Their appeal lies in the availability of materials with moderate loss and lightweight, and the possibility to use cost-effective manufacturing techniques. However,...

In this contribution, a broadband G-band leaky-wave (LW) fed lens antenna with an integrated dielectric grid polarizer is presented. The proposed wideband polarizer unit cell geometry enables its fabrication at frequencies higher than 100 GHz, presenting high transmission properties and low axial ratio (AR). A quasi-Analytic technique based...

Reduction of energy consumption and to increase its generation is necessary, as the population lives in urban settlements consume three-quarters of global resources, and these numbers are continually growing. Building-integrated photovoltaic panels (BIPV) which would assist for the resolution of the problem can be applied by replacing the façade...

Rapidly expanding urban developments are having an inverse relationship on the surrounding urban environment. Facades and the materials that they are composed of can have a large impact on the warming of urban microclimates. By reducing or cooling the external surfaces of a facade a building maybe able to offset its contribution to the urban...
