  2. Impedance parameters - Wikipedia

    en.wikipedia.org/wiki/Impedance_parameters

    The equivalent circuit for Z-parameters of a two-port network. The equivalent circuit for Z-parameters of a reciprocal two-port network. The Z-parameter matrix for the two-port network is probably the most common. In this case the relationship between the port currents, port voltages and the Z-parameter matrix is given by:

  3. Characteristic impedance - Wikipedia

    en.wikipedia.org/wiki/Characteristic_impedance

    The characteristic impedance () of an infinite transmission line at a given angular frequency is the ratio of the voltage and current of a pure sinusoidal wave of the same frequency travelling along the line.

  4. Admittance parameters - Wikipedia

    en.wikipedia.org/wiki/Admittance_parameters

    A Y-parameter matrix describes the behaviour of any linear electrical network that can be regarded as a black box with a number of ports.A port in this context is a pair of electrical terminals carrying equal and opposite currents into and out of the network, and having a particular voltage between them.

  5. Transmission line - Wikipedia

    en.wikipedia.org/wiki/Transmission_line

    Impedance (Z) parameter may defines by applying a fixed current into one port (I1) of a transmission line with the other port open and measuring the resulting voltage on each port (V1, V2) [8] [9] and computing the impedance parameter Z11 is V1/I1, and the impedance parameter Z12 is V2/I1. Since transmission lines are electrically passive and ...

  6. Ray transfer matrix analysis - Wikipedia

    en.wikipedia.org/wiki/Ray_transfer_matrix_analysis

    As one example, if there is free space between the two planes, the ray transfer matrix is given by: = [], where d is the separation distance (measured along the optical axis) between the two reference planes.

  7. Propagation constant - Wikipedia

    en.wikipedia.org/wiki/Propagation_constant

    These include transmission parameter, transmission function, propagation parameter, propagation coefficient and transmission constant. If the plural is used, it suggests that α and β are being referenced separately but collectively as in transmission parameters , propagation parameters , etc.

  8. Quarter-wave impedance transformer - Wikipedia

    en.wikipedia.org/wiki/Quarter-wave_impedance...

    This reflects the fact that open circuit (Z=∞) is dual to short circuit (Z=0). A transmission line that is terminated in some impedance, Z L, that is different from the characteristic impedance, Z 0, will result in a wave being reflected from the termination back to the source. At the input to the line the reflected voltage adds to the ...
