Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre ...

New architecture could be used to create tailored devices that emit or receive only certain frequencies of sound ...

Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a ...

A phase-steered linear array feed for a parabolic cylindrical reflector antenna is considered. The nearly cylindrical wave radiated from this line feed in the Fresnel zone is expressed in terms of the ...

A rigorous coupled-wave model is proposed to simulate the diffraction characteristics of a concentric circular metal grating (CCMG) for an incident transverse-magnetic (TM) wave at terahertz frequency ...
