Electric susceptibility

Index Electric susceptibility

In electricity (electromagnetism), the electric susceptibility (\chi_; Latin: susceptibilis "receptive") is a dimensionless proportionality constant that indicates the degree of polarization of a dielectric material in response to an applied electric field. [1]

Capacitor

A capacitor is a passive two-terminal electrical component that stores potential energy in an electric field.

Causality

Causality (also referred to as causation, or cause and effect) is what connects one process (the cause) with another process or state (the effect), where the first is partly responsible for the second, and the second is partly dependent on the first.

Clausius–Mossotti relation

The Clausius–Mossotti relation expresses the dielectric constant (relative permittivity) εr of a material in terms of the atomic polarizibility α of the material's constituent atoms and/or molecules, or a homogeneous mixture thereof.

Convolution

In mathematics (and, in particular, functional analysis) convolution is a mathematical operation on two functions (f and g) to produce a third function, that is typically viewed as a modified version of one of the original functions, giving the integral of the pointwise multiplication of the two functions as a function of the amount that one of the original functions is translated.
