The conventional radar technology is based on linear detection—i.e., the same transmit and receive frequencies are used. However, with linear radars, difficulties arise when detecting electronic objects with relatively small radar cross section (RC

A retrodirective beamforming system (BFS) based on a Rotman lens is proposed for far-field wireless power transfer at Ka-band. The true-time-delay property of the Rotman lens allows for a wideband operation covering 28–38 GHz. The designed BFS comp

Nonlinear radars can be utilized to detect electronic devices, which are difficult to detect with conventional radars due to their small radar cross sections (RCS). Since the receiver in a nonlinear radar is designed to only receive harmonic or inter

Two-component polyurethane flame-retardant coatings were prepared by blending chlorine-containing modified polyesters (DCAOs) and polyisocyanate. DCAOs used were synthesized by polycondensation of dichloroacetic acid, a flame-retardant aliphatic carb
