Automatic Generation of Subdomain Models in 2-D FDTD Using Reduced Order Modeling
A new method combining a finite difference method and a reduced order model (ROM) algorithm is presented for twodimensional (2-D) electromagnetic problems. The problem space is subdivided into subdomains of a generic type. By discretizing the spatial derivatives in a way similar to the finite-difference in time-domain technique (FDTD), the state equations are written down in each subdomain. Fro...
متن کاملGeneration of FDTD Subcell Equations by Means of Reduced Order Modeling
Adapted finite-difference time-domain (FDTD) update equations exist for a number of objects that are smaller than the grid step, such as wires and thin slots. In this contribution we provide a technique that automatically generates new FDTD update equations for small objects. Our presentation will be focussed on 2-D-FDTD. We start from the FDTD equations in a fine grid where the time derivative...
متن کاملAutomatic 3D Face Modeling Using 2D Active Appearance Models
Although a lot of promising research findings have been studied on 3D face modeling in the past years, it is still a challenge to generate realistic 3D human face models and facial animations. This paper presents a novel approach to model 3D faces automatically from still images or video sequences without manual interactions. Our proposed scheme comprises three steps. First, we offline construc...
متن کاملautomatic verification of authentication protocols using genetic programming
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
15 صفحه اول2D or 3D FDTD Modeling of Photonic Crystal Waveguides?
The aim of this paper is to show how 2D approaches, often used to investigate numerically the real devices as they are faster and simpler respect to 3D techniques, may lead to wrong results in modeling Photonic Crystal structures. As a test case, the determination of the so called Mini Stop Band (MSB) for the fundamental mode in a W1 waveguide is considered. A MSB is found when the structure, r...
