本文所述为通过隔热层进行微波能量耦合的一类微波传输线。更确切地说,本文描述的是关于特别适合于输送微波能量或通过低温冷却器件,达到改善低温致冷器件和它周围的绝热。目前,低温致冷器件在微波频率有着许多应用,实际上,在微波频率还必须用波导管来输送射频能量。由于波导管由一连续的导电体(例如钢或类似材料)构成,同时,它也是好的导热体,所以射频能量通过波导管输送到低温致冷器件时,就会出现严重的绝热问题。以前,致力于减少由于波导管电部分产生的热损耗,并没有取得很大的效果。主要是因为噪声或所需要结构产生的损耗。
This article describes a type of microwave transmission line through the insulating layer of microwave energy coupling. More specifically, what is described herein relates to improved insulation of cryogenic refrigeration devices and their surroundings, particularly suitable for delivering microwave energy or through cryogenic cooling devices. At present, cryogenic refrigeration devices have many applications at microwave frequencies. In fact, microwaves must also use a waveguide to deliver RF energy. Since the wave guide is made of a continuous body of electrical material, such as steel or the like, and it is also a good thermal conductor, a serious problem of thermal insulation can occur when radio frequency energy is delivered to the cryogenic refrigeration device via waveguides. In the past, efforts to reduce the heat loss due to the electrical portion of the waveguide did not achieve great results. Mainly due to noise or loss due to the required structure.
