Stainless-steel waveguides are often used to withstand high temperatures and to provide resistance to eddy currents. GA has manufactured many corrugated stainless-steel waveguides with lengths up to 2.1 meters. The interiors are usually plated with electrolytic nickel to reduce the ohmic loss of the transmitted HE₁₁ mode and associated heating. For high-power pulse lengths longer than about 100 seconds, or with high average transmitted power, cooling is usually required.
