The proposed PPSs have the function of wavelength selection at the critical frequency between the passband and the forbidden band. The critical frequency and the selected wavelength can be tuned by an external DC electric field via the Electro-optic effect.

By employing a polarizer with integrated PRS, FPC antenna can achieve circularly polarized (CP) radiation while maintaining high gain and wide bandwidth characteristics. The proposed polarizer is formed by several grating dielectric and air slabs with an inserted PRS. The dielectric polarizer which realized by 3D printed technology, contribute to 90° phase difference of two orthogonal E fields, resulting in CP performance. The PRS part is used to form FP cavity, resulting in high gain performance. The polarizer is placed over a PCB based feeding source with a quasi-curve reflector using stepped PCB substrates. For validation, a FPC antenna with the proposed PRS integrated 3D printed polarizer operating at 60 GHz is design. Simulated results show that the proposed antenna is a promising candidate for MMW communications.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124696293","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}

We first introduce the image saliency detection model to obtain regional saliency maps for image sub-patches. Then, the importance of each image sub-patch is calculated using a VGG16 network based on its saliency map. Such importance is referred to as the quality weight, which is also the pooling result in the proposed framework. Finally, the prediction quality is defined as the weighted sum of the Structural SIMilarity (SSIM) of all image sub-patches. In the experimental part, we choose the popular LIVE image quality database. The results show that the performance of our model is highly competitive, which indicates the effectiveness of the proposed saliency pooling strategy.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130365764","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}

To improve the gain of a patch, a parasitic ring and a modified multi-layer substrate structure are introduced. As a result, the proposed patch antenna can obtain an enhanced gain and wider impedance bandwidth (IBW) simultaneously. The antenna design is simulated and obtained through a high frequency structure simulator ANSYS HFSS®. According to the simulated results, the proposed antenna can realize an enhanced gain of 9.33 dB at 5.8 GHz, which is 2.31 dB higher than that of an ordinary patch antenna. In addition, the IBW of the patch antenna has been expanded from 1.63% to 4.94%, which is increased by more than twice as much as before.

Due to the refraction and scattering of light in different water types, the colors and shapes of objects can be twisted that are incapable of providing acceptable visual qualities. Thus, it is imperative to develop algorithms to enhance underwater images. Besides, the quality evaluation of underwater images is also exploited as a criteria of underwater image enhancement. In the past decade, the related issues have attracted considerable attention. This paper presents a comprehensive review of the related techniques and their most recent achievements. In particular, we observe a significant trend of applying deep learning in underwater image processing in a small volume of data.
