It requires the development of an optical analogue of an electronic integrated circuit capable of routing, controlling and processing optical signals. Scaling down optical and optoelectronic devices to nanometric dimensions and their integration in photonic circuits requires novel approaches to light manipulation.

The approach combines an advanced electromagnetic induction (EMI) forward model called the normalized surface magnetic charge model (NSMC) with the pole series expansions technique. First, the NSMC is used to generate bi-static EMI data from actual measured mono-static data, and then the pole series expansion approach is employed to localize scattered field singularities, i.e. to find object's location and orientation. Once the object's location and orientations are found, then the total NSMC, which is characteristic of the object, is calculated and used as a discriminant. The algorithm is tested against actual EM-63 time domain EMI data collected at the ERDC test-stand site for an actual UXO. Several numerical results are presented to demonstrate the applicability of the proposed method for UXO discrimination","PeriodicalId":236672,"journal":{"name":"2006 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128390987","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}

If the period of the lattice and the dimensions of the inclusions are small compared with the wavelength, the material is usually considered as an effectively homogeneous medium characterized by effective material parameters (permittivity and permeability). The shape and dimensions of inclusions define the electromagnetic response, which may be rather exotic (negative material parameters, for example) and resonant response. Modelling of typical metamaterial samples with effective material parameters is a non-trivial task, where one has to face several complications as compared with the \"usual\" materials. These complications as well as various possible approaches to effective medium modelling will be discussed in this review presentation","PeriodicalId":236672,"journal":{"name":"2006 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123949672","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}
