function excitation = get_design_excitation(f, L, load)
% Function for getting a specific operating point.
%
%    Parameters:
%        f (float): operating frequency
%        L (float): inductance value
%        load (float): operating point load (relative to full load)
%
%    Returns:
%        excitation (struct): struct containing the operating point
