مقایسه نتایج شبیه‌سازی بلور فوتونی با استفاده از روش FDTD دوبعدی بهبودیافته و FDTD سه‌بعدی
The accuracy of improved two dimensional finite difference time domain method (2D FDTD) is verified by comparing with 3D FDTD method and experimental data. The optimized 60° photonic crystal waveguide bend, used in this study as a test case, is composed of InPGaAs/InP material and air holes and TE polarization is considered. The photonic crystal waveguide bend transmission data was measured...

Quantum-dot Cellular Automata (QCA) has low power consumption and high density and regularity. QCA widely supports the new devices designed for nanotechnology. Application of QCA technology as an alternative method for CMOS technology on nano-scale shows a promising future. This paper presents successful designing, layout and analysis of Multiplexer with a new structure in QCA technique. In thi...
متن کاملQuantum Interference Control of Ballistic Magneto- resistance in a Magnetic Nanowire Containing Two Atomic- Size Domain Walls
The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...
متن کاملA simple form of MT impedance tensor analysis to simplify its decomposition to remove the effects of near surface small-scale 3-D conductivity structures
Magnetotelluric (MT) is a natural electromagnetic (EM) technique which is used for geothermal, petroleum, geotechnical, groundwater and mineral exploration. MT is also routinely used for mapping of deep subsurface structures. In this method, the measured regional complex impedance tensor (Z) is substantially distorted by any topographical feature or small-scale near-surface, three-dimensional (...
متن کاملComparison of Slab and Block Decomposition Strategies for the Two-Dimensional Wigner Monte Carlo Method
Both stochastic and deterministic methods have been applied to solve the one-dimensional Wigner equation. However, only the Wigner Monte Carlo method, using the signed-particle technique [1], has made multi-dimensional Wigner simulations viable thus far [2]; a multidimensional approach is essential for the simulation of realistic semiconductor devices. The primary challenge lies in the fact tha...
