The device layout utilizes alternative plasmonic materials such as transparent conducting oxides and titanium nitride which potentially can be applied for CMOS compatible process. The modulation is obtained by varying the carrier concentration of the transparent conducting oxide layer and exciting plasmonic resonance in the structure. The analysis shows that an extinction ratio of 46 dB/μm can be achieved at the telecommunication wavelength. Proposed structure is particularly convenient for integration with existing insulator-metal-insulator plasmonic waveguides as well as novel photonic/electronic hybrid circuits.","PeriodicalId":151955,"journal":{"name":"2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123787843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work we extend this concept to a surface described by a tensorial electric and magnetic surface impedance, referred to as a tensor Huygens surface. This tensor Huygens surface is now capable of supporting both TE and TM waves for polarization control. Because of this we can model the transmission and reflection of waves through the surface using a four-port S-parameter model. We show an example design of a tensor Huygens surface consisting of rotated loops and dipoles. This design takes a TE-polarized wave and converts it into a circularly polarized wave.","PeriodicalId":151955,"journal":{"name":"2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121786350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that such a structure supports a set of deep subwavelength propagating modes and that it exhibits properties of a single mode waveguide at any fixed frequency which is below the plasma frequency of the wires.
