Electromagnetic Physical Numerical Modeling of a GaN Distributed Transferred Electron Devicea??Based Planar Waveguide THz Oscillator
摘要： The radio frequency (RF) operation of a planar waveguide THz oscillator based on the distributed transferred electron device (DTED) is theoretically investigated by means of 2-D time-domain numerical physical modeling based on the self-consistent solution of the Maxwell and free electron energy-momentum macroscopic transport equations.

A Dual Polarized Magneto-Electric Dipole Antenna Based on Printed Ridge Gap Waveguide Technology
摘要： We review the field of synthetic biology from an analog circuits and analog computation perspective, focusing on circuits that have been built in living cells. This perspective is well suited to pictorially, symbolically, and quantitatively representing the nonlinear, dynamic, and stochastic (noisy) ordinary and partial differential equations that rigorously describe the molecular circuits of synthetic biology. This perspective enables us to construct a canonical analog circuit schematic that helps unify and review the operation of many fundamental circuits that have been built in synthetic biology at the DNA, RNA, protein, and small-molecule levels over nearly two decades. We review 17 circuits in the literature as particular examples of feedforward and feedback analog circuits that arise from special topological cases of the canonical analog circuit schematic. Digital circuit operation of these circuits represents a special case of saturated analog circuit behavior and is automatically incorporated as well. Many issues that have prevented synthetic biology from scaling are naturally represented in analog circuit schematics. Furthermore, the deep similarity between the Boltzmann thermodynamic equations that describe noisy electronic current flow in subthreshold transistors and noisy molecular flux in biochemical reactions has helped map analog circuit motifs in electronics to analog circuit motifs in cells and vice versa via a 'cytomorphic' approach. Thus, a body of knowledge in analog electronic circuit design, analysis, simulation, and implementation may also be useful in the robust and efficient design of molecular circuits in synthetic biology, helping it to scale to more complex circuits in the future.

Substrate-Integrated-Waveguide Power Dividers: An Overview of the Current Technology
摘要： Power dividers are important components of microwave/millimeter wave (mm-wave) circuit design. This article provides a comprehensive review of the state-of-the-art substrate-integrated-waveguide (SIW) power dividers/combiners. SIW technology converts waveguide-like structures into planar form, compensates for the drawbacks of microstrip structures at higher-frequency circuit designs, and minimizes production complexity and costs compared to conventional waveguide structures. An overview of how traditional dividers have progressively adopted the SIW technique is presented and a comparative performance analysis of the divider types and practical paradigm show the future potential of SIW technology.

A novel design of multiplexer based on nano-scale quantum-dot cellular automata
摘要： Quantum-dot Cellular Automata (QCA) is known as one of best alternative technologies for CMOS, on nano-scale dimensions, which allows digital circuits to be designed with high speed and density. In this paper, a novel 2:1 multiplexer in QCA technology is proposed. This proposed QCA multiplexer uses a new formulation based on an introduced MV32 gate. The MV32 gate has three inputs and two outputs and operates based on cell interactions. A multi-layer design for proposed 2:1 QCA multiplexer is provided. The simulation results obtained by the software, QCADesigner 2.0.3, confirm that the proposed multiplexer works well and can be applied as a high performance design, in QCA technology. Moreover, the 2:1 QCA multiplexer is used to create 4:1 and 8:1 QCA multiplexers. The results of comparisons show that the proposed structures have so better performance than many previous designs.
