A DEVICE FOR MEASURING HARMONIC POWER IN A MULTIMODE WAVEGUIDE, SAID DEVICE COMPRISING A SECTION OF HOLLOW ELECTROMAGNETIC WAVE TRANSMISSION LINE, A PLURALITY OF TRANSVERSELY ORIENTED, NARROW IRISES DISPOSED AT EVENLY SPACED POINTS IN THE WALL OF SAID TRANSMISSION LINE, SAID IRISES SAMPLING ONLY THE COMPONENT OF H-FIELD PARALLEL TO THEIR LONG AXES AND BEING TUNED TO A RESONANT FREQUENCY ABOVE THE HARMONIC FREQUENCY BEING MEASURED SO THAT ONLY A RELATIVELY SMALL AMOUNT OF H-FIELD IS SAMPLED, THE NUMBER OF SAID IRISES BEING EQUAL TO THE NUMBER OF FIELD VARIATIONS AT THE WALL OF THE HIGHEST-ORDER PROPAGATING MODE, SAMPLING WAVEGUIDES ATTACHED TO SAID TRANSMISSION LINE AT EACH END OF SAID IRISES FOR RECEIVING AND TRANSMITTING THE POWER EMANATING THEREFROM, AND A CALIBRATED, TUNED DETECTOR HAVING AN OUTPUT AND BEING CONTAINED IN EACH OF SAID SAMPLING WAVEGUIDES FOR MEASURING THE AMOUNT OF POWER PASSING THROUGH SAID IRISES AS AN INDICATION OF THE POWER IN THE MULTIMODE WAVEGUIDE.
