Most of these learning-based methods adopt the empirical training regularized parameter and reconstruction regularized parameter for all input images. This ignores the feature differences among the input low-resolution (LR) images and finally limits the SR performance. To address this problem, we propose an adaptive reconstruction regularization (ARR) algorithm. The reconstruction regularized parameter is adaptively solved by the U-curve algorithm corresponding to each LR remote sensing image, leading to the optimal reconstruction sparse coefficients. To enhance the edges and corners, the high-frequency patches are separately reconstructed after feature extraction. The final SR image is obtained by the superposition of the high-frequency part and the Bicubic up-scaling part. According to the experimental results, our proposed ARR can obtain sharper edges and crispier textures in the recovered SR images than several state-of-the-art methods, demonstrating superior SR performances.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"71 ","pages":"Article 108206"},"PeriodicalIF":4.4,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143686211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method is based on the premise that each subaperture can retain excellent local characteristics within its designated FOV. By assembling these subapertures, we are able to design complex optical systems that achieve high performance with a wide FOV. During the design process, the reflective surfaces of the freeform reflective imaging system are constructed by combining the sampling points of many subapertures and the corresponding normal vectors of these sampling points, to maximize the retention of local characteristics of each subaperture in the combined freeform system. This method can converge at a relatively fast rate compared with traditional design method. The designed optical systems based on the proposed method exhibit good performance and can serve as superior starting structures for further optimization.

Traditional design methodologies for complex plasmonic structures in switching applications rely on empirical or trial-and-error approaches. Nonetheless, the advent of deep learning heralds a paradigm shift, offering a computational vanguard that promises to streamline nanophotonic simulations. To the best of our knowledge, the potential of deep learning methods for designing state-of-the-art plasmonic switches has not yet been identified. This article unveils an approach that harnesses deep learning to not only predict spectral patterns but also to facilitate the inverse design of plasmonic switches, thus introducing a new era of computational nanophotonics. Our methodology demonstrates the operational efficacy of switches via the nonlinear Kerr effect by employing octagonal nonlinear plasmonic ring resonators crafted from metal-insulator-metal waveguides. The forward model presented herein significantly surpasses traditional numerical methods in terms of computational efficiency, meticulously evaluating a spectrum of configurational parameters to predict transmission spectra characterized by pronounced dips. Through inverse modeling, our approach accurately predicts the design parameters aligned with the desired transmission spectra, offering rapid estimations that starkly contrast with the protracted timelines associated with conventional optimization techniques. The mean squared error was minimal for both the forward and inverse models, recording values of 0.026 and 0.015, respectively. These low losses emphatically affirm the prowess of deep learning in both the forward and inverse engineering of plasmonic switches, setting a benchmark for future explorations in the field.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"71 ","pages":"Article 108197"},"PeriodicalIF":4.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
