In contrast to multilayer metamaterials, nanowire metamaterials exhibit an omnidirectional epsilon-near pole (ENP) and an angularly dependent epsilon-near-zero (ENZ), which are both highly absorptive resonances. We also demonstrate large tunability of the epsilon-near-zero resonance in the visible spectrum from 583 nm to 805 nm as the gold nanorod fill fraction changes from 26% to 10.5%. Energy dispersive x-ray (EDX) and X-ray Diffraction (XRD) analyses are used to ascertain the quality of electrochemically deposited Au nanowires prior to and after annealing.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"188 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":"114838109","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}

Computational tools were used to model the interaction between electromagnetic waves and materials with the SCWs structure. The multi-resonance of SCWs is found to be greatly dependent on substrate materials (FR4, air). Insertion of an air layer at the bottom side of the ground plane has the effect of broadening the absorption band, due to the effect of increasing the dielectric resistance by increasing substrate thickness and by decreasing effective permittivity. For the multi-resonance structure of 13 SCWs, a broad bandwidth (6.3-7.6 GHz with respect to 80% absorbance) is predicted. The simulation result is in good agreement with experimental result measured by free space method.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"23 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":"123891002","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}

These structures are an example of a case where a nanoscale simulation over the full device is not reliable and reliance must be placed on a simple design procedure. This paper reports a study of the homogenisation of sub-wavelength waveguide grating structures. It is shown how the properties these waveguides may be accurately modelled using simple design rules. A justification for these rules is found from the exact theory by a judicious choice of approximations. The temporal and spatial dispersive properties of the subwavelength grating waveguide are also evidenced.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"26 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":"122109728","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}

As the hybrid resonance's wave amplitude profile is necessarily the linear superposition of the two original resonant eigenfunctions, the two degrees of freedom can mean that the surface-averaged hybrid resonance amplitude, and its variance, may be separately tunable. It is shown that whereas the average amplitude can serve to match impedance with air, the variance component is “deaf” and serves to absorb the incoming wave energy. The result is a deeply subwavelength structure that can totally absorb the incident wave at tunable frequencies.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"30 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":"133925767","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}
