A sub-terahertz (THz) 3-D printed lightweight compact wideband dual-polarized feed module using an innovative asymmetric wideband orthomode transducer (OMT) is proposed. The OMT is based on a T-shaped ...

Abstract: This letter presents a D-band (110 to 170 GHz) transmit- receive module in 0.13-μm silicon-germanium (SiGe) BiCMOS for phased-array applications. The module includes single-pole double throw ...

Squaring a square sounds simple, but the math behind it is one of the strangest puzzles ever created. It requires cutting a square into smaller squares—all different sizes—with a pattern that doesn’t ...
