2. Scattering parameters - Wikipedia

   en.wikipedia.org/wiki/Scattering_parameters

   The Scattering transfer parameters or T-parameters of a 2-port network are expressed by the T-parameter matrix and are closely related to the corresponding S-parameter matrix. However, unlike S parameters, there is no simple physical means to measure the T parameters in a system, sometimes referred to as Youla waves.

3. S-matrix - Wikipedia

   en.wikipedia.org/wiki/S-matrix

   The S-matrix is closely related to the transition probability amplitude in quantum mechanics and to cross sections of various interactions; the elements (individual numerical entries) in the S-matrix are known as scattering amplitudes. Poles of the S-matrix in the complex-energy plane are identified with bound states, virtual states or resonances.

4. Magic tee - Wikipedia

   en.wikipedia.org/wiki/Magic_Tee

   A magic tee (or magic T or hybrid tee) is a hybrid or 3 dB coupler used in microwave systems. [1] It is an alternative to the rat-race coupler . In contrast to the rat-race, the three-dimensional structure of the magic tee makes it less readily constructed in planar technologies such as microstrip or stripline .

5. Circulator - Wikipedia

   en.wikipedia.org/wiki/Circulator

   ANSI and IEC standard schematic symbol for a circulator (with each waveguide or transmission line port drawn as a single line, rather than as a pair of conductors). In electrical engineering, a circulator is a passive, non-reciprocal three- or four-port device that only allows a microwave or radio-frequency (RF) signal to exit through the port directly after the one it entered.

6. List of named matrices - Wikipedia

   en.wikipedia.org/wiki/List_of_named_matrices

   S matrix — a matrix in quantum mechanics that connects asymptotic (infinite past and future) particle states. Scattering matrix - a matrix in Microwave Engineering that describes how the power move in a multiport system. State transition matrix — exponent of state matrix in control systems.

7. Admittance parameters - Wikipedia

   en.wikipedia.org/wiki/Admittance_parameters

   Admittance parameters or Y-parameters (the elements of an admittance matrix or Y-matrix) are properties used in many areas of electrical engineering, such as power, electronics, and telecommunications. These parameters are used to describe the electrical behavior of linear electrical networks.

8. Channel state information - Wikipedia

   en.wikipedia.org/wiki/Channel_state_information

   In wireless communications, channel state information (CSI) is the known channel properties of a communication link.This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering, fading, and power decay with distance.

9. Talk:S-matrix - Wikipedia

   en.wikipedia.org/wiki/Talk:S-matrix

   Here the S-matrix is given for a particular value of wave vector.That is why the S-matrix is 2 by 2.As there is infinite number of wave vector, the S-matrix is in general infinite dimensional block diagonal matrix.Each block is 2 by 2,correspond to particular value of wave vector.Dibyendum 09:44, 1 December 2014 (UTC)
