- Form factor: Physical size of a device including linear dimensions, mounting and connector standards, and other parameters that categorize the item as belonging to a mechanically compatible family.
- Time domain: Add brief definition or description
- Frequency domain: Add brief definition or description
- Electromagnetic spectrum: The range of electromagnetic waves covering all frequencies and wavelengths.
- Infrared light: In physics and engineering, a non-visible portion of the electromagnetic spectrum ranging from wavelengths of 750 nm to 1 mm, between the darkest visible red and the shortest submillimeter wave radar
- Visible light: Electromagnetic radiation of a wavelength that is detectable by the human eye.
- Ultraviolet: The part of the electromagnetic spectrum between the visible light and X-ray regions
- Radio: Transmission and reception of information, which can be voice, data or imagery over electromagnetic radiation in free space (i.e., wireless). The information is modulated onto a carrier wave See also Radio
- Radar: (acronym for "radio detection and ranging") A technique used for detecting and tracking targets, navigation, imagery, and special applications. See also Radar
- Antenna: Please do not use this term in your topic list, because there is no single article for it. Please substitute a more precise term. See Antenna (disambiguation) for a list of available, more precise, topics. Please add a new usage if needed. See also Antenna
- Radiofrequency MASINT: Collection and processing of intelligence information derived from unintentional electromagnetic radiation from targets of interest
- Multipath: Add brief definition or description
- Superheterodyne: A form of reception in which the frequency of an incoming signal is mixed with a locally generated signal and converted to an intermediate frequency in order to facilitate amplification and the rejection of unwanted signals.
- Software-defined radio: Radio communication system where components that have typically been implemented in hardware are instead implemented using software on a personal computer or other embedded computing devices.
- Operation RAFTER: A measurement and signature intelligence (MASINT) technique that allowed a remote monitor to determine, passively, the frequency to which a radio receiver was tuned; revelation of the technique allowed it to be prevented
- Polarization: Please do not use this term in your topic list, because there is no single article for it. Please substitute a more precise term. See Polarization (disambiguation) for a list of available, more precise, topics. Please add a new usage if needed.
- Wavelength: For a repeating phenomenon such as a radio signal with a given frequency, the wavelength is the length, in meters, of a single repetition
- Dipole: Add brief definition or description
- Chaff (electronic warfare): A passive, disposable radar countermeasure using strips of metal foil or aluminized plastic, cut to match the wavelength of the expected radar, and used to send false reflections back to the radar receiver
