Radiophysics

Radiophysics is a branch of physics focused on the theoretical and experimental study of certain kinds of radiation: its emission, propagation, and interaction with the medium.

The term is used in the following major meanings:
*study of radio waves (the original area of research)
*study of radiation used in radiology [ [http://www.medcyclopaedia.com/library/radiology/chapter03.aspx?s=radiophysics&mode=1&syn=&scope= "Radiophysics" article] in "Medcyclopaedia", online version of the "Encyclopaedia of Medical Imaging"]
*study of other ranges of the spectrum of electromagnetic radiation in some specific applications

Among main applications of radiophysics are radio communications, radiolocation, radioastronomy, and radiology.

Branches

*Classical radiophysics deals with radio wave communications and detection
*Quantum radiophysics (physics of lasers and masers; Nikolai Basov was the founder of quantum radiophysics in the Soviet Union)
*Statistical radiophysics
