Furthermore, they inherently support significant long-range interactions and radiation to the surrounding medium. Hence they are fundamentally different from traditional QP structures governed by the Harper's model or the almost-Mathieu operator. We present a mathematical framework for QP particle chains and study their electrodynamics. They support guided modes that exhibit a complex interaction with the light cone, and possess a two-dimensional fractal-like structure in the frequencywavenumber space thus making the unique definition of modal phase velocity impossible. However, a well-defined group velocity is revealed due to the fractals inner structure. We also show initial study of non-reciprocal QP structures.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125439776","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}

Extinction spectra are recorded while scanning a single nano-particle through a lens's focal plane. We show a direct correlation between the focal wavelength and the longitudinal chromatic focal shift through analysis of the variations between scanned extinction spectra at each scan position and peak extinction over the entire scan. The method has been tested on achromat and apochromat objectives using aluminum nano-particles.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125546339","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}

This behavior can induce a series of optical effects such as all-angle negative refraction. In the presence of an external field, a non-reciprocal lateral shift on reflection is also possible. We illustrate these effects using the example of MnF2. In this crystal both the angle of refraction and the Goos-Hänchen shift become tunable when an external magnetic field is applied.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116009688","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}

Applying a composite right left handed transmission line, and open circuit termination load, the antenna operates at triple band frequencies, 1.8 GHz, 3.5 GHz and 5.8 GHz with total size 21×25 mm2 (only 27% compared to conventional microstrip antenna). A compromise between the proposed antenna's compact size and efficiency is made, as a result the antenna provides a maximum directive gain equals 1.37 dB, 2.76 dB and 3.61 dB, respectively. The proposed antenna can serve WiMAX and GSM applications efficiently.
