The proposed scheme provides uniform and selective powering modes. In either powering mode, the field is isotropic, which removes the WPT-restrictions on placement and orientation of the energy harvester. The design process has three main steps, randomness creation, frequency selection, and waveform generation. We validate the proposed scheme in a lab lyophiliser’s (freeze-drier) chamber. First, we create a random electromagnetic environment using mechanical stirring. Then, we evaluate this randomness in terms of the average to minimum power ratio. To select an appropriate frequency for the WPT system, we consider randomness and power uniformity. To maintain randomness, we extract the lowest usable frequency of the chamber using a Goodness of Fit test; this is found to be 6 GHz. As for the power uniformity, we plot the standard deviation (STD) of a large sample of the received powers at different locations. This plot is used to select the frequency based on an arbitrary uniformity level in terms of STD. At 6 GHz a 2.5 dB standard deviation is calculated. To enable the selective powering mode, we propose the electromagnetic time reversal (EMTR) technique. We show that EMTR can, theoretically, focus 97% of the energy on 0.5λ-diameter area in an ideally random environment.","PeriodicalId":328717,"journal":{"name":"2019 IEEE 20th Wireless and Microwave Technology Conference (WAMICON)","volume":"471 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132893837","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 design, fabrication process and characterization results are presented. 3D printing quality, namely feature size and dimensional accuracy, was improved by utilizing well-characterized laser machining techniques. The laser machining process enables the control of the dimensions of micro-dispensed conductive traces down to a few micrometers. CPW lines are printed on a fixed-fixed beam and can be extended over the bridge across devices such as a low noise amplifier MMIC chip or another interconnect layer underneath. Acrylonitrile butadiene styrene (ABS) and CB028 conductive silver paste are utilized to fabricate the CPW lines on suspended beams over an air cavity. Simulated and measured S-parameters up to 30 GHz for an interconnect are presented. The conductor width, ground width, and slot width are 160 μm, 260 μm, and 20 μm, respectively. The measured transmission line loss of the suspended CPW line is 0.26 dB/mm at 30 GHz.","PeriodicalId":328717,"journal":{"name":"2019 IEEE 20th Wireless and Microwave Technology Conference (WAMICON)","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127360830","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}

Its behavior involves coupling of electromagnetic waves to spin waves oscillations in ferrite material on which no traditional model is available to provide quantitive prediction of its performance. In this talk, we will present a nonlinear circuit model for FSL device design. The dominant magnetic-behaviors of FSL devices are translated into equivalent circuits with parameters rigorously determined from fundamental physics. The spin motions as well as the ferromagnetic resonance (FMR) are modeled by RLC parallel circuits with parameters derived from Polder’s tensor and Kittel’s equations. The exchange coupling between spins is modeled by an inductor added between adjacent RLC circuits based on quantum spin theory. The nonlinear cross-frequency coupling from signal at ω to spin waves at ω/2 is represented by a pendulum model that predicts the parametric oscillations of spins. The circuit units are cascaded to describe the spin wave propagation inside the magnetic material, and transmission line parameters are added finally to describe the RF signal propagation. The simulation results match the measurement results published, and the model successfully predicts the threshold power level, nonlinear insertion loss, time delay, and frequency selectivity of the device. The modeling approach opens a new paradigm in simulating strong, nonlinear wave-matter coupling in certain RF devices, in which the macroscopic behavior of the device is linked to quantum physics that is happening in nanometer dimensions.","PeriodicalId":328717,"journal":{"name":"2019 IEEE 20th Wireless and Microwave Technology Conference (WAMICON)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123125994","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}
