The perfect absorbers consist of periodic array of metal particles,SU8 dielectric spacing layer and a thicker metallic bottom layer. Through the LC model and the finite element numerical simulation methods,we studied the performance of the absorber. With finely tuned parameters,such like the thickness of the SU8 dielectric layers,the periodicity of the metal particles array,and the length of the metal particles, the near perfect absorption up to ~ 100% at the wavelength range between 20 μm to 30 μm for far infrared can be achieved. Based on these results,further design for the double-resonator absorber has been provided. Dual band perfect absorption can be accurately and independently obtained by adjusting the particle size of the upper and the lower metal layers. Moreover,the wavelength of the perfect absorption is also almost independent of the incident angle. These phenomena can be attributed to the multiple reflections between the thick metallic bottom layer and metal particle layers separated by SU8 dielectric layer,which can also be explained using a LC model as the resonant absorption in the metal-dielectric-metal cavities.","PeriodicalId":50181,"journal":{"name":"红外与毫米波学报","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66393343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Erf-BP, an improved model based on the Gaussian error function of BP neural network, was used to develop remote sensing models for estimating leaf nitrogen content. Then the scaling conversion function during downscales from canopy to leaf spectral was derived according to principles of geometric optics model. These relations were used during downscales from the canopy reflectance of Hyperion image to leaf spectral for leaf nitrogen content estimation. Finally, forest structural parameter leaf area index (LAI) was used to obtain canopy nitrogen content from leaf level. The results showed that the best Erf-BP. neural network model with testing accuracy of 76.8597% includes 8 neurons in hidden layer. Using scaling conversion function to estimate canopy spectra at 670nm and 865nm, correlations (R-2) between modeling spectra and measurements were 0.5203 and 0.4117 respectively. Correlation coefficient between estimated leaf nitrogen content and measurements was 0.7019. This method provides a good reference for more rapid and accurate estimation of leaf and canopy nitrogen.","PeriodicalId":50181,"journal":{"name":"红外与毫米波学报","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2013-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69888210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
