Radio frequency (RF) tomography is proposed to detect underground voids, such as tunnels
or caches, over relatively wide areas of regard. The RF tomography approach requires a set …

This paper presents a solvent-based, mild method to prepare superhydrophobic, carbon
nanofiber/PTFE-filled polymer composite coatings with high electrical conductivity and reports …

We propose a new analog self-interference cancellation (SIC) technique for in-band full-duplex
transmission in single-antenna systems. We use an RF circulator to separate transmitted (…

The design of modular, passive, and static artificial metasurfaces to be used as
electromagnetic skins (EMSs) of buildings for improving the coverage in urban millimeter-wave …

Multipath is exploited to image targets that are hidden due to lack of line of sight (LOS) path
in urban environments. Urban radar scenes include building walls, therefore creating …

A printed dipole antenna is designed with two parasitic elements loaded by embedded
resonators to provide reconfigurable patterns. The embedded resonators in the parasitic …

A new method for the synthesis of single-bit reconfigurable passive electromagnetic skins (1RP-EMSs)
featuring advanced beam shaping capabilities is proposed. By using single-bit …

We review machine learning and its applications in a wide range of electromagnetic problems,
including radar, communication, imaging and sensing. We extensively discuss some …

A new method to address radar target detection problems in multipath environments is
considered. The novelty of the proposed method is that it exploits prior knowledge on the …

An ultrawideband multibeam microwave lens antenna operating from 8 to 18 GHz is proposed.
The antenna consists of four excitation ports connected to a parallel plate waveguide …
