Among antennas for Industrial, Scientific and Medical (ISM band) applications at 433 MHz, quarter-wave monopole is a reasonably good trade-off between size, gain, and cost. The electrical performance of the monopole is largely dependent on the quality of the ground plane (size and conductivity),...

Unconventional folded shielded coplanar waveguide (FS-CPW) has yet to be fully investigated for tunable dielectrics-based applications. This work formulates designs of FS-CPW based on liquid crystals (LC) for electrically controlled 0-360° phase shifters, featuring a minimally redundant...

The growing interest in the modulation of phase (and amplitude) of microwave and millimeter-wave signals has been spurred by the emerging 5G/6G phased-array beam-steering applications for which liquid crystal is one of the enabling technologies. A problematic journal paper on liquid...

This work contributes a systematic survey and complementary insights of reflecting Brownian motion and its properties. Extension of the Skorohod problem's solution to more general cases is investigated, based on which a discussion is further conducted on the existence of solutions for a few...
