Sets the vacuum wavelength \lambda_0. The vacuum wavelength is specified in units of meter, \units{m}.

Traditionally for waveguide problems, the vacuum wavelength is used to specify the angular frequency,

\begin{eqnarray*} \omega & = & \frac{2\pi c}{\lambda_0}, \end{eqnarray*}

as used within time-harmonic Maxwell’s equations, see TimeHarmonic and parent section PropagatingMode. Here, c is the speed of light in vacuum.
