TRANSMISSION LINE WINDOWS

摘要

A window assembly for use with electromagnetic waveguides includes a window (3) and a housing (4). The window (3) has impermeable layers (33) and (34) which are bridged by a reticulum (35) of ceramic material with internal spac es which form a continuous flow path for coolant. The window is received in an opening in the housing (4) which is surrounded by an inwardly-directed flang e having a peripheral recess opposed to the window (3) to improve the microwav e performance of the window.
