A trapezoidal shape periodically corrugated metallic grooves, which shows enhanced confinement of surface wave; have been used in the implementation of transition and filter. In the design of back to back transition, matching between QTEM and SSPP mode has been achieved using gradient grooves. The developed transition has been used to experimentally characterize a ring resonator where ring has been corrugated with periodical array of trapezoidal shaped grooves. This ring resonator shows multiple pass bands at different frequencies within the specified frequency range.

This paper presents performance analysis of MLGNR based interconnects on equivalent single-conductor (ESC) model for local/intermediate and global level of chip interconnects at 13.4 and 21 nm technology nodes. The number of conducting channel variations with Fermi energy and interconnect width are analyzed first. The performance of metallic armchair (AC) and Zig-Zag (ZZ) based MLGNR interconnects is computed employing equivalent single conductor (ESC) model in terms of delay, average power consumption, and power-delay product (PDP). The computed results for metallic armchair and Zig-Zag MLGNR are compared against Copper based interconnects. It is observed that MLGNRs offer significantly improved delay ratio, average power reduction, and lower PDP values than copper based interconnects.","PeriodicalId":259227,"journal":{"name":"2017 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130814868","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}

Here, we use sparse regression using a sequential thresholded leastsquares algorithm to determine the fewest relevant terms from a large set of available terms required to accurately represent the dynamics of RF PAs. The proposed approach develops a framework for behavioral modeling of RF PAs, taking into advantage, the advances in sparsity techniques which balances the model accuracy with complexity. We show that, for similar modeling performance, the proposed method requires fewer coefficients than the standard memory polynomial model and simplified Volterra based models.","PeriodicalId":259227,"journal":{"name":"2017 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134474281","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 near field of the array radiator is obtained from its far field pattern as a spherical modal expansion (SME). The requisite number of spherical modes characterizing the array are treated as co-located plane wave sources radiating into the shaped dielectric lens and analyzed using geometrical optics (GO). The total field at any point on a spherical surface surrounding the lens is the sum of individual plane wave contributions. These are easily transformed to far field using a SME. Presented in this effort are computations using the hybrid technique for hemi-spheroidal and hemi-spherical lenses irradiated by 1×2 and 2×2 array in C and X-bands that are compared with results using an EM Flow solver (HFSS). Significantly the hybrid procedure is validated with measured results obtained in an anechoic chamber that shows a far better agreement, as compared to EM flow solver. Notably the computation time required by hybrid method is nearly 18 times less compared to the simulation time of EM Flow solver.","PeriodicalId":259227,"journal":{"name":"2017 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116999978","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}

This is possible by utilizing the defected ground structures (DGSs).

DGSs can be implemented in different shapes; hence, the K and Q-factor of these DSGs are realized with different values depending on the DGS shape. In return, the achievable WPT efficiency can be maximized by careful selection of the DGS shape and dimensions depending on the system efficiency and distance requirements.","PeriodicalId":259227,"journal":{"name":"2017 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131333729","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 speed up the filter design flow, we introduced metamodels for design optimization and variability analysis tasks.
