Accurate plane-wave excitation in the FDTD method
(IEEE, 1997)Different techniques are developed to implement plane-wave excitation on the finite-difference time-domain (FDTD) method, such as the initial-condition, the hard-source, and the connecting-condition techniques, for the ... -
Analysis of an arbitrary profile reflector antenna having resistive-type surface-H-polarization case
(IEEE, 2008-06-07)A regularization-based numerical solution is obtained for arbitrary-shape conic section profile reflector antenna in 2-D, for the H-polarization case. New point is that the reflector surface is assumed a resistive-type ... -
Analysis of an arbitrary-profile, cylindrical, impedance reflector surface illuminated by an E-polarized complex line source beam
(VSP BV, 2014)Electromagnetic scattering from a cylindrical reflector surface having an arbitrary conic section profile is studied. We assumed an electrically thin layer antenna illuminated by a complex line source in E-polarization ... -
Analytic modeling of loss and cross-coupling in capacitive micromachined ultrasonic transducers
(IEEE, Piscataway, NJ, United States, 1998)The structural loss mechanism of capacitive micromachined ultrasonic transducer (cMUT) is investigated using finite element analysis and the normal mode theory. A single micromachined transducer membrane on an infinite ... -
Aspects of computational homogenization at finite deformations: a unifying review from Reuss' to Voigt's Bound
(American Society of Mechanical Engineers (ASME), 2016)The objective of this contribution is to present a unifying review on strain-driven computational homogenization at finite strains, thereby elaborating on computational aspects of the finite element method. The underlying ... -
Comparative evaluation of absorbing boundary conditions using Green's functions for layered media
(Institute of Electrical and Electronics Engineers, 1996-02)Absorbing boundary conditions are comparatively studied using the Green's functions of the vector and scalar potentials for multilayer geometries and general sources. Since the absorbing boundaries are introduced as ... -

Constructing convex directions for stable polynomials
(IEEE, 2000)The constructions of convex directions based on phase-derivative interpretations were obtained for Hurwitz-stable polynomials. The phase-derivative conditions were based on the sensitivity of root-locus associated with the ... -
A dynamic control law for the wave equation
(Elsevier, 1994)We consider a system described by the one-dimensional linear wave equation in a bounded domain with appropriate boundary conditions. To stabilize the system, we propose a dynamic boundary controller applied at the free end ... -
Dynamical phase transitions in totally asymmetric simple exclusion processes with two types of particles under periodically driven boundary conditions
(American Physical Society, 2016)Driven diffusive systems have provided simple models for nonequilibrium systems with nontrivial structures. Steady-state behavior of these systems with constant boundary conditions have been studied extensively. Comparatively ... -
An efficient algorithm for the single machine total tardiness problem
