Full-resolution 3D imaging for concrete structures with dual-polarization GPR

Automation in Construction, 2021
Ground-penetrating radar (GPR) is one of the most commonly used technologies for concrete inspection. This technology's main limitation is that its raw data are complex and only understood by GPR experts.

Reflection Removal Using Dual-Polarization and Saliency in Millimeter-Wave and Terahertz Imaging

IEEE Transactions on Geoscience and Remote Sensing, 2021
Passive millimeter-wave and terahertz (MMW/THz) imaging is a significant technique used in personal security inspection and scene surveillance. However, a human body generally generates an obvious reflection on the floor, which may have negative ...

Dual-Polarized Gap Waveguide

2020 IEEE USNC-CNC-URSI North American Radio Science Meeting (Joint with AP-S Symposium), 2020
Aiming to introduce a new guiding structure, this work presents dually polarized gap waveguide (DPGWG) operating in transverse electromagnetic (TEM) mode. To show the proof of concept, two waveports are connected at the ends of waveguide and transmission (for both horizontal and vertical polarization) is observed.

Enhanced dual polarization directional coupler for dual polarization beam forming networks

2000 IEEE MTT-S International Microwave Symposium Digest (Cat. No.00CH37017), 2002
Directional couplers and fixed phase shifters are the key components for the realization of beam forming networks. Usually a beam forming network feeds the antenna with two linear and orthogonal polarizations. Dual polarization components can be used to reduce complexity and size of a beam forming network.
