Almost simultaneously, the commercial implementation of an effective response surface technique was complemented by the discovery of the space mapping concept that promised electromagnetically validated, near optimal solutions at the expense of only a few high-fidelity full-wave simulations. Simplified models, even coarse electromagnetic models, could now be iteratively “mapped” on-the-fly to full-wave models through the 1995 aggressive space mapping algorithm. In this paper, we offer a brief overview of further advances to date, including space mapping, response correction techniques, simulation-based tuning, as well as feature-based modeling and optimization.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"56 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85162362","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 integrated mixer converts a ramp signal with a stabilized local oscillator (SLO) signal to the RF output signal. The usage of a mixer reduces the frequency multiplication factor of the ramp signal and hence improves the phase noise at 160 GHz. The fixed frequency local oscillator for the up-conversion has a comparably small phase noise level compared to the ramp input signal and does not contribute significantly to the total phase noise level at 160 GHz. Apart from the synthesizer, the MMIC also includes a power amplifier with a maximum output power of 2 dBm, two efficient integrated antennas with a wide radiation pattern, and an IQ-receiver. Two FMCW radar responses recorded with a bandwidth of 20 GHz show the dynamic range of this sensor and its near range behavior. The compact SiGe MMIC requires only a chip area of 1.4mm × 1.0mm and consumes 285mW from a 3V power supply.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"13 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80490975","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 demonstrate the general capability to image electronic variations within nanomaterials using nanowires of VO2 and Si as model systems. For VO2 we image the temperature-dependent metal-insulator domain coexistence that arises due to the built-in strain in substrate-clamped wires. In Si NWs integrated into a transistor device architecture we observe large increases in the source-drain current with the tip passing over the wire, correlated with variations in the SMM signal. We attribute this effect to local rectification of the microwave signal by the local tip-sample Schottky junction.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"28 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80435807","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 derivation of this prototype is based on a suitable transformation of an asymmetric lattice network, generated through a sequence of matrix rotations of the coupling matrix of the folded canonical prototype. It is shown that the lattice network is a generalization of the canonical cul-de-sac form, which is obtained when the reflection zeros are all imaginary. We have also verified that the cul-de-sac forms are possible only when the reflection zeros are all imaginary (or in para-conjugate pairs). The lattice network (or the one with frequency-dependent couplings) represents a possible alternative to the cul-de-sac forms in the synthesis of star-junction multiplexers, when the synthesized filters exhibits complex reflection zeros.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"20 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77749721","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}

In addition to performing frequency-domain measurements, for the first time, an ultra-wideband THz Time-Domain Spectroscopy (THz-TDS) system is utilized to characterize the radiated signal in time-domain.
