Claim 1
Independent Claim
114 words
A MICROWAVE TRANSMISSION LINE SYSTEM COMPRISING A VARIABLE IMPEDANCE CELL LOCATED BETWEEN A SOURCE AND A LOAD, SAID CELL FOR PROVIDING A VARIABLE IMPEDANCE COMPRISING: A CONDUCTIVE WALL PARTIALLY BOUNDING A REGION, MEANS FOR MAINTAINING SAID REGION SUBSTANTIALLY EVACUATED, AN ELECTROMAGNETIC WAVE GENERATOR COUPLED TO SUPPLY ELECTROMAGNETIC ENERGY TO SAID REGION, THE LEVEL OF SAID ENERGY BEING SUFFICIENT TO INDUCE A MULTIPACTOR DISCHARGE IN SAID REGION ALONG A PATH HAVING AT LEAST ONE END TERMINATING AT SAID WALL, AND A MAGNETIC FIELD SOURCE FOR APPLYING TO SAID REGION A STEADY MAGNETIC FIELD, SAID MAGNETIC FIELD BEING ORIENTED PERPENDICULARLY TO SAID PATH, SAID MULTIPACTOR DISCHARGE HAVING A MAXIMUM VALUE WHEN THE MAGNETIC FIELD IS ZERO.
