A diode with a semiconducting material, such as germanium or silicon, for one electrode, and a fine wire "whisker''...
waveguide
A waveguide is a physical structure or device that is designed to confine and guide electromagnetic waves, such as radio...
radio-frequency linear accelerator
A device used to accelerate the electrons in a free-electron laser by channeling microwave energy into waveguide cavity...
remote sensing
Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on...
electro-optic radar

gas laser
One of the first lasers to find practical application. Generally, the pumping mechanism is an electric discharge, although...
calorimeter
An instrument used to measure the change of heat content of a system by measuring microwave power in terms of generated heat.
attenuation
Attenuation refers to the gradual loss or reduction of intensity, force, or magnitude of a particular property as it...
microwave holography
The holographic recording of the pattern formed by two sets of coherent microwaves that interfere at a scanning plane. A...
directed energy
Directed energy refers to a type of energy that is emitted and transferred in a controlled direction. The term is often...
undulator magnet
A device used in a free-electron laser to convert the electron-beam's energy into microwave laser radiation by creating a...
free-carrier photoconductivity
Photoconductivity that may be extended as far as the microwave region because of the absorption of photons by electrons.
synthetic aperture radar
Imaging radar that increases the sweep of its along-track (or azimuth) capacity by measuring not only the time delay of the...
maser
An acronym for microwave amplification by stimulated emission of radiation. Predecessor to the laser, the maser or...
terahertz
Terahertz (THz) refers to a unit of frequency in the electromagnetic spectrum, denoting waves with frequencies between 0.1...
terahertz radiation
Electromagnetic radiation with frequencies between 300 GHz and 10 THz, and existing between regions of the electromagnetic...
microwave phototube
A device designed to detect microwave modulation and to mix modulated and unmodulated laser beams. It consists of a...
metamaterial
Metamaterials are artificial materials engineered to have properties not found in naturally occurring substances. These...
microwave
An electromagnetic wave lying within the region of the frequency spectrum that is between about 1000 MHz (1 GHz) and 100,000...
microwave mapping
The pattern of microwave field intensity that can be obtained by detecting the minute expansion of a microwave absorber slab...
optical clock
An optical clock is a highly precise and advanced timekeeping device that relies on the oscillations of electromagnetic...
potassium titanyl phosphate
A crystalline material with a high electro-optic coefficient, capable of operating at short wavelengths, with applications...
riez photodiode
A photodiode having a conducting grid that covers the surface of the photodiode junction and intercepts and wastes some of...
electrodeless discharge tube
A device consisting of an airtight quartz tube that holds the material to be analyzed. When a high-frequency electrostatic...
infrared
Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but...
spectral signature
A spectral signature, in the context of remote sensing and spectroscopy, refers to the unique pattern or characteristic...
frequency comb
A frequency comb is a precise and regular series of equally spaced spectral lines, or frequencies, that are generated with...
