Then, full-wave simulation is used to obtain the filter layout in microstrip technology. Analysis shows that the second undesired stopband is far away from the first stopband frequency. If the microstrip lines and capacitor are chosen properly, the second stopband is at least forty times the first stopband frequency. A prototype BSF is fabricated with the stopband at 1.04 GHz. The upper passband of the filter extends up to 12.11 GHz. At the same time, significant size reduction is obtained.

The unit cell of the proposed absorber contains two L shape patches with an inner ring conductor on the top of the FR4 substrate and copper laminates on the bottom surface. The absorber thinness is only 2 mm. This absorber has a wideband absorptivity response from 7.31 GHz to 10.7GHz without using any lumped circuit components. The maximum absorptivities of 99.71% and 99.9% are detected at 7.68 GHz and 10.01 GHz respectively. Several designed parameters are studied. The absorption characteristic of the proposed design absorber is observed by varying oblique incidence for TE and TM polarization. It is found that wideband absorption characteristics maintain up to 300 incidence angle for both TE and TM mode. In comparison to currently existing microwave absorbers, the proposed construction is extremely thin.","PeriodicalId":226787,"journal":{"name":"2021 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123621703","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}

The mountable design of an aluminum-based cylindrical cavity records a quality factor of more than 9000 and provides an easy assembly of samples to be tested. The linear region of the cavity precisely provides the identification of dielectric samples in the range of 1 to 20 within $sim$ 99 % of accuracy using the standard cavity formulation. On the other hand, the proposed machine learning approach works effectively in the non-linear region of the cavity and predicts the dielectric properties accurately in the wide range dielectric constant starting from 20-45 with a typical error of 0.35 %. The non-linearity of the cavity output is modeled using the cascade feedforward architecture of Artificial Neural Network (ANN) for multiinput variables extracted from the simulations. The model is trained using a well-known Bayesian regularization algorithm with an adequate number of samples and subsequently tested over a large sample of novel test input. The mean square error of test samples in the range of 10-4 and correlation coefficient (R) near 1 demonstrates the effectiveness of the approach in dielectric testing using the proposed cavity.","PeriodicalId":226787,"journal":{"name":"2021 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123470389","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}

The outer side of sensing arm of MZI is facilitated with 10 nm thick layer of gold nanoparticles (AuNPs) to improve the sensitivity. Further, the specificity of sensing arm towards glucose molecules is enhanced by coating a layer of glucose oxidase (GOx).
