Synonym index of cooperation.

A group of two bits.
Note: The four possible states for a dibit are 00, 01, 10, and
1
1. Synonym diad.

An optical filter that reflects one or more optical bands or wavelengths and transmits others, while maintaining a nearly zero coefficient of absorption for all wavelengths of interest.
Note: A dichroic filter may be high-pass, low-pass, band-pass, or band rejection.

A mirror used to reflect light selectively according to its wavelength.

Abbreviation for direct inward dialing.

1. A substance in which an electric field may be maintained with zero or near-zero power dissipation, i.e., the electrical conductivity is zero or near zero.
Note 1: A dielectric material is an electrical insulator.
Note 2: In a dielectric, electrons are bound to atoms and molecules, hence there are few free electrons.
2. Pertaining to a substance that has… (Read More →)

See interference filter.

In the radio regime, a lens made of dielectric material that refracts radio waves in the same manner that an optical lens refracts light waves.

1. Of an insulating material, the maximum electric field strength that it can withstand intrinsically without breaking down, i.e., without experiencing failure of its insulating properties.
Note: The theoretical dielectric strength of a material is an intrinsic property of the bulk material and is not dependent on the configuration of the material or the electrodes with which the field is… (Read More →)

A waveguide that consists of a dielectric material surrounded by another dielectric material, such as air, glass, or plastic, with a lower refractive index.
Note 1: An example of a dielectric waveguide is an optical fiber.
Note 2: A metallic waveguide filled with a dielectric material is not a dielectric waveguide.
