Successive Interference Cancellation (SIC) is a technique used by a receiver in a wireless data transmission that allows decoding of two or more packets that arrived simultaneously (in a regular system, more packets arriving at the same time cause a collision).
Self-interference cancellation (SIC) is a signal processing technique that enables a radio transceiver to simultaneously transmit and receive on a single channel, a pair of partially-overlapping channels, or any pair of channels in the same frequency band.
A susceptor is a material used for its ability to absorb electromagnetic energy and convert it to heat (which in some cases is re-emitted as infrared thermal radiation). The electromagnetic energy is typically radiofrequency or microwave radiation used in industrial heating processes.
The silicon carbide (SiC) substrate and magnesium pellets are on the top of the susceptor. Hybrid physical–chemical vapor deposition (HPCVD) is a thin-film deposition technique, that combines physical vapor deposition (PVD) with chemical vapor deposition (CVD).
The susceptor is made from a material resistant to the temperature and metalorganic compounds used, often it is machined from graphite. For growing nitrides and related materials, a special coating, typically of silicon nitride or tantalum carbide , on the graphite susceptor is necessary to prevent corrosion by ammonia (NH 3 ) gas.
Use of sic greatly increased in the mid-20th century. [8] For example, in United States state-court opinions before 1944, sic appeared 1,239 times in the Westlaw database; in those from 1945 to 1990, it appeared 69,168 times, over 55 times as many. [2] Its use as a form of ridicule has been cited as a major factor in this increase. [2]
The term was coined by C.P. Steinmetz in a 1894 paper. [1]In some sources Oliver Heaviside is given credit for coining the term, [2] or with introducing the concept under the name permittance. [3]
Silicon carbide (SiC) is used as a susceptor in microwave furnaces, a commonly used abrasive, and as a refractory material. Silicon nitride (Si 3 N 4) is used as an abrasive powder. Steatite (magnesium silicates) is used as an electrical insulator. Titanium carbide Used in space shuttle re-entry shields and scratchproof watches.
