Various joint constructions were designed and tested to provide pressure-assisted low-resistance contact between flanges of the metal-coated 3D printed U-shaped waveguide shell and on-PCB ground plane that serves as one of the guide's walls. The above is an alternative to the originally proposed through-hole screw joint that although low resistance requires extra parts and a more complicated assembly. Exemplary separable ball and cantilever snap-fit joints were developed and integrated at different pitches into test vehicles fabricated for the experimental study being a through-patch microstrip to AF-WG transition in back-to-back configuration operating within 9 GHz to 12 GHz bandwidth with long waveguide section in-between. The obtained results show that a ball joint can provide comparable performance in terms of total power loss of the circuit to a screw joint when properly spaced making it superior to use for highly-integrated circuits.","PeriodicalId":215592,"journal":{"name":"2022 52nd European Microwave Conference (EuMC)","volume":"31 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124261764","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}

Each of the multi-resonant stages contributes to the overall transfer function one pole and two transmission zeros (TZs). Thus, the proposed three-stage BPF configuration exhibits a transfer function shaped by three poles and six TZs. A detailed RF design methodology using analytical equations is provided for each multi-resonant AWLR stage. Various design examples for each stage and the overall three-pole/6-TZ BPF are presented. For proof-of-concept demonstration purposes a three-pole/six-TZs filter prototype was designed, manufactured and measured at 916.6 MHz.

We apply the Lasing Eigenvalue Problem (LEP) approach, which delivers the mode-specific eigenvalue pairs, namely the frequencies and the threshold values of the QW gain index for the plasmon and the wire modes of nanolaser. In our work, we use quantum Kubo formalism for the graphene conductivity and classical Maxwell boundary-value problem for the field functions. The technique involves the resistive boundary conditions, the separation of variables in the local coordinates, and the addition theorem for the cylindrical functions. We derive separate determinantal equations for four different classes of symmetry of the lasing supermodes and solve them numerically. Our investigation of the mode frequencies and thresholds versus the graphene and QW parameters shows that plasmon supermodes have lower frequencies and thresholds than the wire modes provided that the QW radius is smaller than 10 µm, however in thicker wires they are comparable. The plasmon-mode characteristics are tunable using the graphene chemical potential. These results open a way for building essentially single-mode plasmonic nanolasers and their arrays.","PeriodicalId":215592,"journal":{"name":"2022 52nd European Microwave Conference (EuMC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116703416","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 two arrays cover a one-dimensional angular steering range of ± 30°, and thus a total steering range of ± 60° around nadir. Simulation results of the realized gain patterns of the antenna module are presented for all steering angles at 20 GHz and 30 GHz.

Three different resonator types (dielectric TM-mode, dielectric quasi- TM -mode and coaxial resonators) are implemented in order to increase the out of band rejection of the filter. Each of the chosen resonator types are used to implement one of the passbands in the filter response. The proposed topology leads to three real frequency axis transmission zeros between adjacent bands without the need for any complex cross coupling or coupling with a negative sign. Additionally, the topology reveals possibilities for an adaption of the bandwidth and distance between the individual passbands. The presented filter design leads to a large spurious free range up to 3.5 times the center frequency of the center band.","PeriodicalId":215592,"journal":{"name":"2022 52nd European Microwave Conference (EuMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128693614","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}
