Abstract
Sensitive millimeter wave diagnostics need often to be protected against unwanted radiation like, for example, stray radiation from high power Electron Cyclotron Resonance Heating applied in nuclear fusion. A notch filter based on a waveguide Bragg reflector (photonic bandgap) can provide several stop bands of defined width within up to two standard waveguide frequency bands.
