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...

This work presents the design of a reduced instruction set computing (RISC) microprocessor in a four-stage pipeline architecture. The nuts and bolts of each block including timing diagrams are elaborated. To be more specific, a hardware solution to pipeline hazards is proposed and verified, i.e....

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...

Originated from a miniature online bookseller to a massive superstore company raking in $75.5 billion in the first fiscal quarter of 2020 despite the surge in COVID-19, Amazon is arguably a frontrunner in e-commerce over the course of its spectacular 25-year history. This paper conducts a...
