As commercial, military/aerospace, and other communications designs extend into the millimeter wave (mmWave) spectrum, engineers must adapt their testing procedures and require more from instruments ...

This circuit provides different ways to measure the current-voltage phase displacement of a line-powered ac load. The classic approach for sensing an ac load's current requires a transformer or ...

“Optical interferometry plays an essential role in precision metrology such as in gravitational wave detection, gyroscopes, and environmental sensing. Weak value amplification enables reaching the ...

Based on the needs of engineering applications, this monograph presents a variety of direction-finding and ranging methods based on short baseline array and using unambiguous phase difference ...
