The double corrugated waveguide slow wave structure (SWS) and sheet beam are presented by simulation. The SWS parameters, the parallel electron beam current and inclination angle, and the permanent guiding magnetic field are chosen in the system through optimization using electromagnetic codes and PIC codes. Because of the inclination of the electron beam, the electrons are closer to the SWS and can have stronger interaction with the electric field in order to obtain higher output power. Besides, thicker electron beam can be used when the electron beam is inclined, which also leads to a higher output power. Moreover, there are no absorbers at the SWS ends so that strong reflections will exist at beam inlet and outlet. The simulation results show that the maximum output power is 229.8 mW at frequency of 397 GHz is achieved with beam voltage 10 kV, beam current 120 mA and guiding magnetic field of 1.0 T.","PeriodicalId":197451,"journal":{"name":"2019 Photonics & Electromagnetics Research Symposium - Fall (PIERS - Fall)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128320766","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}

One of the main keys of the transceiver systems is the voltage-controlled oscillator (VCO) which is considered the main building block of the phase locked loop (PLL) frequency synthesizer. Realizing VCO with wider tuning range (TR) and low phase noise at the mm-wave frequency range is considered a challenging task. In this work, a cross coupled differential pair Class-C voltage controlled oscillator is employed to improve the phase noise across wider tuning range. The proposed design is based on the 0.13 µm SiGe BiCMOS process technology. A new varactor circuit is proposed to extend the tuning range. In order to extend the tuning range of the VCO more and more, a bank of fixed capacitors is added to the LC tank with a controlled MOS switches. Multiple tuning ranges are achieved using the proposed LC tank. The EM effects of the paths and interconnections through the layout are taken into considerations before fabrication. The proposed LC VCO achieved maximum post-layout phase noise of −97 (dBc/Hz) at 1 MHz offset from the carries. In addition, it achieves a wide tuning range between 18.2 GHz to 26 GHz. Moreover, the proposed VCO consumes only 12 mW from 1.2 voltage supply.","PeriodicalId":197451,"journal":{"name":"2019 Photonics & Electromagnetics Research Symposium - Fall (PIERS - Fall)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127262141","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 self-generated magnetic field acts as an internal insulation barrier within the device and prevents electrical breakdown, which is important for gigawatt range operation. S-band MILO design, analysis, simulation and parameter optimization has been studied and presented in this paper. The presented MILO design consists of a three-stage choke cavity, three- cavity extraction region, and a slow wave structure. An attempt is made to increase the efficiency by using the concept of a tapered extraction region which improves wave extraction at the output a beam dump disk which acts as a tool to properly utilize the load current for self-insulating magnetic field generation. The disk is supported by four appropriately sized and positioned stubs for impedance matching, and hence improve output power. A parametric optimization run on both the structural and beam parameters provides the best values for operation. The results presented are obtained using the commercial software CST Studio, using its 3D Particle-In-Cell (PIC) simulation method. Eigenmode analysis is also performed on the slow wave structure to get dispersion curves for resonant frequency of MILO and verify its operation in n-mode. Simulation results reveal that the S-band MILO generates dominant TM01 mode at the desired frequency of 3.4 GHz. The results show a stable frequency response throughout the time of operation, as well as a high dominant mode efficiency of 98%. The generated wave has a peak power of 6.8 GW and a peak efficiency of 22.5% with the application of an input pulse voltage of 530kV and 57kA current.","PeriodicalId":197451,"journal":{"name":"2019 Photonics & Electromagnetics Research Symposium - Fall (PIERS - Fall)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127329664","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}
