Enhanced transmission loss introduced by tunable components in reconfigurable spoof surface plasmon polarition (SSPP) transmission line (TL) reduces the efficiency of microwave systems. To solve this problem, a low-loss reconfigurable SSPP TL which can manipulate sub-wavelength electromagnetic fields is proposed.

2023年5月1日 · Draft Standard for Serial SCADA Protection Protocol (SSPP) This standard defines a cryptographic protocol to provide integrity, and optional confidentiality, for cyber security of substation serial links.

In this paper, we propose a new SSPP TL structure, named as air-filled SSPP TL. The air-filled SSPP TL can substantially reduce the dielectric loss, since the waves propagate through the air rather than through a lossy dielectric medium.

SSPP. Both short and long term goals should be established and measures to gauge accomplishment should be described. The role of the other organizations in the safety areas, and their interface with the Safety organization within the property should be defined. For example, the Operations/Transportation

2024年9月14日 · 人工表面等离子体激元 (SSPPs)是沿金属和介质表面传播的一种特殊的表面电磁模式,在金属内部表现为群电子振荡,在金属外部表现为沿界面传播的电磁振荡。 SSPPs具有场显著增强、强色散等特性, 因此, SSPPs波导具有低损耗和低剖面等特点,近年来被广泛用于微波、太赫兹器件中。 SSPP天线的研究主要集中在漏波天线和端射天线,而对谐振天线的研究较少,基于SSPP谐振天线具有体积小、阻抗匹配方便、多频段工作等优点, 因此基于奇偶模SSPP谐振天 …
