Radiophysics
Encyclopedia
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:
Among main applications of radiophysics are radio
communications, radiolocation
, radioastronomy, and radiology.
Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

Radio
Radio is the transmission of signals through free space by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space...
communications, radiolocation
Radiolocation
Radiolocating is the process of finding the location of something through the use of radio waves. It generally refers to passive uses, particularly radar—as well as detecting buried cables, water mains, and other public utilities. It is similar to radionavigation, but radiolocation usually...
