We demonstrate the design, fabrication, and large-signal RF characterization, via active Load/Source-Pull (L/S-P), of a SBD on single-crystalline diamond (SCD). This is the first time a fully-integrated RF SBD has been fabricated and characterized via high-power impedance matching. The SBD was developed on a p−/p+ boron-doped SCD wafer. Active L/S-P was performed at 10 GHz for an input power (Pin) of 34 dBm, attaining an output power (Pout) of 33.3 dBm, yielding a loss of 0.7 dB under matching conditions and an RF power density of ~ 375 W/mm2. These RF power levels are higher than those available in the literature for SBDs and show that diode large-signal characterization via active L-P can potentially play a significant role in the design of multipliers, rectifiers, and detectors that aim to deliver high $mathrm{P}_{mathrm{out}}$ without thermal degradation.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"100 1","pages":"297-300"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81391357","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 systolic and diastolic BPs can be calculated by the reflective pulse transit time (R-PTT) using the BP computation algorithm. Instead of using conventional PTT, the R-PTT is re-defined as the propagation time interval between the forward and reflected pressure waves observed at the radial artery area in this paper. It can be then extracted from the wrist pulse waveform, which is remotely measured by the radar sensor. The BPs of a 23-year-old female have been continuously monitored for 8 days and compared with the commercial cuff-based BP monitor. The measured mean difference (MD) and standard deviation (SD) of the proposed BP radar sensor are O.55±5.45 mmHg (MD±SD) and -2.26±3.93 mmHg (MD±SD) for systolic and diastolic BPs, respectively.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"39 1","pages":"647-650"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82492300","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}

At these frequencies, surface roughness of waveguide components (a side effect of both standard fabrication and 3-D printing) has a pronounced role. Yet, in FDTD, this effect is still modeled through the time-consuming Monte-Carlo method. This paper presents a new approach with distinct advantages over the state of the art. Reflection and transmission through rough slabs is modeled with FDTD and an efficient polynomial chaos expansion of the statistical fields in and around the rough surface. We demonstrate the computational efficiency and accuracy of this technique, which can model both the usual excess attenuation due to small-scale roughness and diffuse scattering effects.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"56 1","pages":"864-867"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78639116","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 verify our design concept, six different types of couplers with 1/2 and 1/3 coupling ratio and termination impedance of 25 Ω, 50 Ω and 100 Ω are designed, fabricated and measured.
