| 摘 要： | 提出了一种适合在一些特定环境下做为光波传输手段的新颖光信道——利用金属壁腔传输信息。该信道适合于需要在两个不同实体间传输信息的特定结构中，首先提出了信道模型，然后讨论了不同结构参数对信道吸收损耗和带宽的影响，对所设计的具体信道的带宽和损耗进行了计算，并比较了不同金属镀层对损耗的影响。说明了合理选择信道参数信道可达到宽带宽低损耗的要求，因此该信道可运用于需在环型腔体中传输信息的结构中。

| Abstract: | A new optical channel is presented. Cyclindrical metal closed void is introduced for light wave transmission in some special structure, compared to the traditional optical channel and optical fiber,the channel is more suitable for transmitting information in armillary lacunar. The absorption loss and bandwidth are discussed when parameters value are changed, The result is given under specified parameters. To decrease the absorption loss, metallization is used in the channel. |
