Parameters:

• length – of the waveguide.

• length_undercut_spacing – from undercut regions.

• length_undercut – length of each undercut section.

• length_straight – from where the trenches start to the via_stack.

• length_straight_input – from input port to where trenches start.

• cross_section – for waveguide ports.

• cross_section_heater – for heated sections. heater metal only.

• cross_section_waveguide_heater – for heated sections.

• cross_section_heater_undercut – for heated sections with undercut.

• with_undercut – isolation trenches for higher efficiency.

• via_stack – via stack.

• port_orientation1 – left via stack port orientation.

• port_orientation2 – right via stack port orientation.

• heater_taper_length – minimizes current concentrations from heater to via_stack.

• ohms_per_square – to calculate resistance.

• straight – straight component.
