Attenuation coefficient in dielectric in rectangular waveguide¶

A rectangular waveguide is a rectangular metal waveguide capable of supporting waves propagating along it.

attenuation_coefficient¶: attenuation_coefficient of the waveguide.

Symbol:: alpha
Latex:: \(\alpha\)
Dimension:: 1/length

waveguide_impedance¶: wave_impedance in the waveguide.

Symbol:: eta
Latex:: \(\eta\)
Dimension:: impedance

medium_impedance¶: wave_impedance in the dielectric medium.

Symbol:: eta_0
Latex:: \(\eta_{0}\)
Dimension:: impedance

wavelength¶: wavelength.

Symbol:: lambda
Latex:: \(\lambda\)
Dimension:: length

loss_tangent¶: dielectric_loss_tangent.

Symbol:: tan(delta)
Latex:: \(\tan \delta\)
Dimension:: dimensionless

law¶

alpha = pi / lambda * eta / eta_0 * tan(delta)

Latex:: \[\alpha = \frac{\pi}{\lambda} \frac{\eta}{\eta_{0}} \tan \delta\]
