	Abstract:Based on the CST software, numerical simulations are carried out for the frequency response in a coaxial Bragg structure with tapered ripples. Results show that the bandwidth of the frequency response can be either narrowed or expanded, which depends on the tapering angle, and that the residual side-lobes of the frequency response can be effectively suppressed by employing the windowing-function technique. These characters of a tapered coaxial Bragg structure are favorable to improvement of the performance as a reflector or a filter in its application.

	4. An Efficient Analysis of the Long-wire antenna With Matched Impedance Using MPIE/MoM

	Electrics, Communication and Autocontrol Technology 08 June 2008

	Abstract:In this paper, the method mixed potential integral equation (MPIE) combined with half rooftop basis function is used to analysis the long-wire antenna with matched loading terminations. MPIE is a kind of integral equations in Method of Moment (MOM) and can effectively deal with models with terminal loads. The contribution of this method is that we can take proper measures to the boundaries of the model by using the half basis function, which allows the current to flow across the edges. All of the elements in MoM impedance matrix, only the elements in the first and second rows need calculating for the structure of straight line according to the principle of reciprocity and symmetry. The results of current, voltage along the line and the radiation field calculated by this method agree well with the results of theoretical value and transmission-line theory(TL).

	5. Influence of Gradient on Bandwidth in a Coaxial Bragg Structure

	Abstract:The Bragg structure can be used as a reflector ,also can be used as a filter. When it as a reflector to construct resonator, the selectivity of a Bragg reflector can be increased by making the bandwidth narrower; when it as a filter , the bandwidth is more broad, the filter bound more broad. To change the bandwidth of a coaxial Bragg structure with inner and outer conducting wall gradient sinusoidally corrugated is investigated. Numerical study illustrates that the bandwidth can be changed obviously when the outer wall and the inner rod are corrugated with a same gradient sinusoidally corrugated.

	Abstract:An efficient method is presented to design the evanescent wave amplification exactly by cascading two layers of periodic series-shunt capacitors and and inductors, which simulate a bilayer of magnetic and electric plasmas. Based on the presented method, equivalent lumped parameters of circuit structures are retrieved, from which the evanescent-wave amplification (EWA) is obtained at a designed frequency. Full-wave simulations show that the relative offset of the EWA frequency is less than 0.1%. The structure has been fabricated and measured, and the measurement results have good agreements with the simulation results. The proposed method can be used to design other periodic circuit structures, and the exact design of EWA can be used in the fabrication of novel components.

	Abstract:System development in advanced SOPC allows considerable flexibility, both during development and in field use. In this paper, we explores the design of a Bluetooth—Ethernet adapter based on SOPC. Two levels of parallelisms are analyzed for an efficient implementation with the computing part on Nios II embedded soft processor and the audio stream preprocessing part on customized hardware. It begins with review of the development procedure of SOPC, and then the design mechanism of IIS controller IP core and software based on Nios II CPU. In our studies, we developed the embedded system in an Altera Cyclone FPGA, together with Lightweight TCP/IP stack and µC/OS-II system. Results of simulation and test show that the design is successful.

	8. Optical waveguide ring resonator with multi-turn structure

	Abstract:Resonator micro optic gyro (R-MOG) is a high accuracy inertial rotation sensor based on the Sagnac effect. Optical waveguide ring resonator (OWRR) is the core-sensing element in R-MOG. Calculations show that the shot noise limited sensitivity of the gyro can be improved by introducing the multi-turn structure into the ring when the excess loss of the crossed waveguides is lower than a critical value. The OWRR with two turns is fabricated on silica waveguide by low pressure chemical vapor deposition (LPVCD) method. Measurements show that the finesses of the one-turn resonator and the two-turn resonator are 50.8 and 20.0 respectively. The great degeneracy of the finesse is due to that the excess loss of the crossed waveguides is high as 0.899dB. Further analysis shows when the excess loss is lower than 0.3dB, the gyro sensitivity will be increased by means of the OWRR with multi-turn structures.

	9. Stress Electric-Field Dependent TDDB Characteristics of Ultra-Thin HfN/HfO2 Gate Stack with 0.9 nm EOT

	Abstract:In this paper, ultra thin CVD HfO2-gated nMOS capacitors (nMOSCs) with EOT~0.9 nm were fabricated. The time-dependent dielectric breakdown (TDDB) characteristics of the 0.9 nm HfO2 gate stack were studied under constant voltage stress (CVS). Area scaling consistent with Weibull statistics as in SiO2 was observed in the gate stack, demonstrating that intrinsic effects dominate time-dependent dielectric breakdown (TDDB) characteristics of the ultra thin HfN/HfO2 gate stack. For the first time, different TDDB characteristics under gate injection with low and high CVS were demonstrated in the sub-1 nm EOT HfO2 gated devices. The results show that interfacial layer initiated breakdown dominates the TDDB under low CVS and HfO2 bulk initiated breakdown under high CVS. A new breakdown model is proposed to explain the new demonstrated TDDB characteristics.

	Abstract:Several preconditioning techniques, such as Jacobi、SSOR and ILU0, are used to accelerate the convergence of iterative methods, such as CG and GMRES, which are used to solve the large system of linear equations resulted from the time-domain finite-element methods (TDFEM). Convergence properties and the time used of these conventional preconditioning techniques are also compared and analyzed. The cylindrical cavity partially filled with dielectric rod and the PML terminated waveguides are simulated. Numerical results show that the ILU0 preconditioned method converges the fastest and costs the smallest time in TDFEM compared with other preconditioning techniques when computing the same number of time steps.
