	Susceptance - Biocrawler
		In electrical engineering, the susceptance (B) is the imaginary part of the admittance.
		In SI units, the susceptance is measured in siemens.
		Note: The susceptance is NOT the inverse of the reactance.

	What is susceptance? - a definition from Whatis.com - see also: B
		Susceptance (symbolized B) is an expression of the ease with which alternating current (AC) passes through a capacitance or inductance.
		Conductance and susceptance combine to form admittance, which is defined in terms of two-dimensional quantities known as complex numbers.
		As the inductance of a component increases, its susceptance becomes smaller negatively (that is, it approaches zero from the negative side) in imaginary terms, assuming the frequency is held constant.

	What is admittance? - a definition from Whatis.com - see also: Y
		Susceptance, denoted B, is an expression of the readiness with which an electronic component, circuit, or system releases stored energy as the current and voltage fluctuate.
		Admittance is the vector sum of conductance and susceptance.
		Susceptance is conventionally multiplied by the positive square root of -1, the unit imaginary number called symbolized by j, to express Y as a complex quantity G - jB

	Ridged Waveguide and Transitions
		Consequently a small impedance discontinuity will exist, and since root finding is straight forward, the need for an approximation is avoided and so the trancendental equation in [1] is preferred.
		In order to calculate the cut off wave length for the dominant mode, it is first necessary to establish the normalized susceptance that exists at the edge of the ridge.
		per equation (3) p400, we then have the following terms to be included in the expression for normalized capacitive susceptance at the edge of the ridge.

	Smith Chart Basics - Microwave Encyclopedia - Microwaves101.com
		The stub is now a 125-ohm line (50/0.4) and its susceptance varies less over the band, so it has lower Q. Note that the unnormalized values are rarely needed, normalized values may be renormalized by the ratio of the characteristic impedances involved.
		The technique is simple: move along the transmission line to rotate the mismatch to the unity resistance (conductance) circle and insert the appropriate type and length of stub in series (shunt) with the main line to move along this circle to the origin.
		Then, the characteristic impedance and length of the stub is chosen such that its input susceptance is equal and opposite to the main line susceptance indicated on the unity conductance circle.

		The susceptance corresponding to this distance, at the wavelength being used, is obtained by the usual cotangent relation.
		If the key is open, the susceptance of the hole, obtained from H and the wavelength, is added, and this new susceptance is used to calculate a new R representing the distance to the pressure node.
		Here the susceptance of the hole, l/2/PI/H (where H has been read from data as C(K,1)) is added to the susceptance corresponding to the distance R. Line 230 then calculates the new R corresponding to this total susceptance.

	NEJM -- Tympanometry in the diagnosis of middle-ear effusion
		To evaluate this technic as a means of detecting middle-ear effusion, we studied acoustic susceptance and conductance in 91 children.
		The mean value for susceptance at 660 Hz gave best results: 83 of 84 tympanograms of ears with middle-ear effusion had values less than 0.16 millimhos (mmho).
		We conclude that a mean acoustic susceptance at 660 Hz less than 0.16 mmho in a child four months of age or older indicates the presence of middle-ear effusion.

	Remote protection of three phase distribution transformers - Patent 4745512
		By monitoring the susceptance of the distributor cable and connected load, the positive sequence monitoring at the primary sub station is rendered relatively insensitive to changes in positive sequence current arising from the energising of substantial new load.
		Conveniently, the time related susceptance values are calculated using the measured values for positive sequence phase angle biased by a predetermined compensation angle selected to produce zero monitored susceptance increase for normal fault free increases in load current.
		Alternatively, where only an increase in the negative susceptance value is being detected, the values of negative susceptance from successive sampling periods are stored and the value for the latest sampling period compared with stored values from previous sampling periods to detect increases.

	Conductance, Susceptance, and Admittance
		Conductance's electrical symbol is G. Susceptance (symbolized with a B) is the opposite of reactance.
		That is to say, capacitive susceptance is 1 divided by the capacitive reactance, and inductive susceptance is 1 divided by the inductive reactance.
		You'll be glad to know (perhaps) that the formula for calculating admittance is identical to that of impedance, except that you use conductance and susceptance to calculate admittance (not resistance and reactance, as you do with impedance).

		Likewise, figures of conductance (G) and susceptance (B) are most useful in circuits where the two types of opposition are not mixed, i.e.
		Again, we see a certain logic to the naming of this new term: while impedance is a measure of how much alternating current is impeded in a circuit, admittance is a measure of how much current is admitted.

	Window-Based Susceptance Models for Large-Scale RLC Circuit Analyses (Site not responding. Last check: )
		Due to the increasing operating frequencies and the manner in which the corresponding integrated circuits and systems must be designed, the extraction, modeling and simulation of the magnetic couplings for final design verification can be a daunting task.
		In this paper we demonstrate a localized, window-based extraction and simulation methodology that employs the recently proposed susceptance (the inverse of inductance matrix) concept.
		A critical aspect of this simulation efficiency is owed to a susceptance-based circuit formulation that we prove to be symmetric positive definite.
