- plasmapy.formulary.dielectric.permittivity_1D_Maxwellian_lite(omega, kWave, vth, wp)
The lite-function for
permittivity_1D_Maxwellian. Performs the same calculations as
permittivity_1D_Maxwellian, but is intended for computational use and, thus, has data conditioning safeguards removed.
omega (array_like of real positive values) – The frequency, in rad/s, of the electromagnetic wave propagating through the plasma.
kWave (array_like of real values) – The corresponding wavenumber, in rad/m, of the electromagnetic wave propagating through the plasma.
Real) – The plasma frequency, in rad/s.
chi – The ion or the electron dielectric permittivity of the plasma. This is a dimensionless quantity.
