The approximate modal interface–solution space projection is a combined domain decomposition–model order reduction method for an efficient broadband full-wave simulation of multilayer printed circuit boards. The method features a high efficiency and full-wave accuracy for modern electronic designs. In this paper, a number of enhancements to our previously reported algorithm are presented. The e...

five-zone simulating moving bed (smb) system, designed for ternary separation, is a modified form of standard four-zone smb which is only effective in binary separation. it was reported in literature that the five-zone smb separates the extract-ii stream with a lower purity value than that of raffinate and extract-i streams. to address this issue, five zone smb was designed, using safety margin...

in this study, the capabilities of wawewatch-iii and mike21-sw for predicting the characteristics ofwind-generated waves in hormuz strait are evaluated. the numerical models have been set up using input data including gfs wind with 5° spatial resolution and 6 hours time intervals, along with the etopo1 bathymetry data with 2 arc-minute spatial resolutions. the results of the two model simulatio...

The application of an unconditionally stable locally one-dimensional finite-difference time-domain (LOD-FDTD) method for the full-wave simulation of semiconductor devices is described. The model consists of the electron equations for semiconductor devices in conjunction with Maxwell’s equations for electromagnetic effects. Therefore the behaviour of an active device at high frequencies is descr...

An ultra-wide-band (UWB), stripline-fed Vivaldi antenna is characterized both numerically and experimentally. Three-dimensional far-field measurements are conducted and accurate antenna gain and efficiency as well as gain variation versus frequency in the boresight direction are measured. Using two Vivaldi antennas, a free-space communication link is set up. The impulse response of the cascaded...

We are working toward actualizing a real-time 3D modeling system that uses a sensor network consists of many 1mm3-class sensor nodes in plastic clay. This paper focuses on 1mm3-class small antenna and discusses the feasibility of near-field communication with such small antennas. In order to clarify communication characteristics for evaluating the feasibility, we designed 1mm3-class spiral ante...

In this paper we present techniques for the real-time simulation and rendering of liquids. Appropriate approximations to a full 3D simulation are applied to reduce the numerical complexity. Fluid flow is described by the 2D Navier-Stokes equations; wave effects are represented according to the wave equation for shallow water waves on a height-field. A novel mechanism for coupling flow and wave ...

This paper presents a probabilistic analysis of an iterative two-way paraxial scheme for the simulation of wave propagation in random media. This scheme has the computational cost of the standard one-way paraxial wave equation but has the accuracy of the full wave equation in a regime beyond the classical paraxial regime. More precisely, it accurately predicts the statistics of the reflected wa...
