The advantage of this kind of TE (or TM) cloak is that only two components of mu (or epsiv) are spatially variant, which makes it possible to realize with two-dimensional (2D) magnetic (or electric) metamaterial. The effects of perturbations, such as the loss of the metamaterial and the minor change of the parameters, on the performance of this cloak are quantitatively analyzed.

It is showed that the 1DPCs can possess a similar zero average index (zero-nmacr) gaps, the edges of the zero-nmacr gap are weakly dependent on the incident angle, scale length and the polarization of electromagnetic wave. When an impurity is introduced, a defect mode appears inside the zero-nmacr gap with a very weak dependence on incident angle. A transmitted light pulse in such photonic crystals can experience a positive or negative group delay and hence a subluminal, ultraslow or superluminal propagation with small distortions at different frequency point such as at the lower gap edge, at the defect mode and in the bandgap, respectively.","PeriodicalId":345360,"journal":{"name":"2008 International Workshop on Metamaterials","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129881682","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}

However, its major drawback is that its training process is computationally expensive, which makes it hard to be efficient and precise simultaneously. In this paper, an efficient HMM-based similarity search scheme is proposed with an innovative training algorithm using small size of training data composed of only distinct subsequences, which is very useful for the metamaterial design. Experiment results show that the training time of our method can be reduced extremely to 1% of that of conventional methods. Furthermore, our HMM-based model is more stable with threshold fluctuating, which make it more feasible in practice.","PeriodicalId":345360,"journal":{"name":"2008 International Workshop on Metamaterials","volume":"22 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132410933","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}

Ultra-low group velocity dispersion has been also found in such waveguides. On the other hand, we have found out omnidirectional resonances in various kinds of 1D photonic crystal heterostructures possessing the zero-phieff/zero-nmacr gap, and in a simple sandwich structure.
