设计了一种内多层介质的圆形金属空芯波导，重点研究了红外线中HE11模的低损耗传输。涂层的电介质材料的厚度的选择和变化的影响进行了讨论，并示出是小的最小可达到的传输损耗。模式结构和传输特性也澄清一般类的空心波导通过使用归一化的表面阻抗和导纳。
A circular metallic hollow waveguide with inner dielectric multilayers is designed with the emphasis on low-loss transmission of the HE 11 mode for the infrared. The effects of absorptions and variations of thickness of coated dielectric materials are discussed and are shown to be small on the minimum attainable transmission losses. Mode structure and transmission properties are also clarified for the general class of hollow waveguides by using a normalized surface impedance and admittance.
