κ = ω \sqrt{\frac{ε \cdot μ}{2}} {[\sqrt{1 + (\frac{σ}{ε \cdot ω})} - 1]}^{\frac{1}{2}}

$kappa = omega sqrt(( epsilon * mu )/2) [sqrt(1 + ( sigma /( epsilon * omega ) ) ) -1]^(1/2)$

This equation describes the imaginary portion ( $κ$ $kappa$ ) of the complex wavenumber¹ ( $˜ k$ $tilde k$ ) of an electromagnetic wave in a conducting medium. $κ$ $kappa$ is a spatial angular frequency, normally given the units of rad/m. vCalc doesn't currently have any other unit options for angular spatial frequency, but feel free to request them using the "contact us" button at the bottom.

For more information on $˜ k$ $tilde k$ and how it's use, please refer to EM waves (attenuating) in a conductor.
