Therefore, many traditional physical methods represented by transformation optics have been studied to achieve total transmission. However, these methods have strict limitations on the size of the photonic structure, and the calculation is complex. Here, we exploit deep learning to achieve this goal. In deep learning, the data-driven prediction and design are carried out by artificial neural networks (ANNs), which provide a convenient architecture for large dataset problems. By taking the transmission characteristic of the multi-layer stacks as an example, we demonstrate how optical materials can be designed by using ANNs. The trained network directly establishes the mapping from optical materials to transmission spectra, and enables the forward spectral prediction and inverse material design of total transmission in the given parameter space. Our work paves the way for the optical material design with special properties based on deep learning.</p></div>","PeriodicalId":53467,"journal":{"name":"Journal of Electronic Science and Technology","volume":"20 1","pages":"Article 100146"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1674862X21001087/pdfft?md5=12e8675e610329ee74dddd36dddf33c7&pid=1-s2.0-S1674862X21001087-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43410300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And the characteristics of the Smith-Purcell radiation in these structures were presented. Simulation results show that SPPs are excited on the bottom surface of Au substrate grating grooves and LSP is stimulated on the upper surface both of Au ribbons grating grooves and Au grating grooves. Owing to the irreconcilable contradiction between optimizing the grating diffraction radiation efficiency and optimizing the SPPs excitation efficiency in the Au substrate grating, only 40-times enhancement of the radiation intensity was obtained by excited SPPs. However, the LSP enhanced structure overcomes the above problem and gains much better radiation enhancement ability, with about 200-times enhancement obtained in the Au ribbons grating and more than 500-times enhancement obtained in the Au grating.

To balance the capacity and performance of caches, this paper proposes an instruction cache (ICache) architecture based on divide-by-2 memory banks (D2MB-ICache). The control circuit and memory banks of D2MB-ICache work at the central processing unit (CPU) frequency and the divide-by-2 CPU frequency, respectively, so that the capacity of D2MB-ICache can be expanded without lowering its frequency. For sequential access, D2MB-ICache can output the required instruction from memory banks per CPU cycle by dividing the memory banks with a partition mechanism and employing an inversed clock technique. For non-sequential access, D2MB-ICache will fetch certain jump instructions one or two more times, so that it can catch the jump of the request address in time and send the correct instruction to the pipeline. Experimental results show that, compared with conventional ICache, D2MB-ICaches with the same and double capacities show a maximum frequency increase by an average of 14.6% and 6.8%, and a performance improvement by an average of 10.3% and 3.8%, respectively. Moreover, the energy efficiency of 64-kB D2MB-ICache is improved by 24.3%.</p></div>","PeriodicalId":53467,"journal":{"name":"Journal of Electronic Science and Technology","volume":"19 4","pages":"Article 100121"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jnlest.2021.100121","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41270667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
