Very high frequency (VHF) refers to the radio frequency electromagnetic waves ranging from 30 to 300 MHz with corresponding wavelengths ranging from 1 m to tens of meters. VHF is widely used for FM broadcasting, television broadcasting, military and local mobile radio transmissions, traffic control...
Very high frequency Very high frequency (VHF) Cycles per second: 30 MHz to 300 MHz Wavelength: 10 m to 1 m Very high frequency (VHF) is the radio frequency
The present author has previously published a series of papers at STAIF exploring the interactions of very-high frequency gravitational waves (VHFGWs, typically around 3 GHz) with superconductors. One important design concept is a novel variable-focus lens that would be invaluable in the design of...

This paper considers the scattering of very high frequency (VHF) electromagnetic waves from a random weakly corrugated surface by the perturbation method. The calculations show that the scattering has a resonant nature, i.e., only certain Fourier components of the surface shape are responsible for ...
