Piezoelectric resonators have been generally modeled with the electrostatic approximation, which does not predict any electromagnetic (EM) wave behavior. In this research, we develop and validate a fully coupled finite-element (FE) model to study interaction between elastodynamics electrodynamics. We simulate EM radiation from vibrating piezoelectric resonator excited by harmonic shears via d <sub xmlns:mml="http://www.w3.org/1998/Math/MathML"...
The finite-element method (FEM) has been one of the major numerical techniques for electromagnetics (EM) ever since introduction spurious-free edge element. On other hand, a so-called least-squares FEM(LSFEM) is becoming increasingly popular due to its unique properties. For instance, generated stiffness matrix positive definite. Effort made apply this node-element-based LSFEM model EM problems, mostly in theoretical aspect. In paper, we will use normalized Maxwell's equations incorporated...
Research on electrically-small antennas has been active for a long time, but so far it is still challenging to approach the Chu's limit that sets constraint between quality factor and size of an antenna. Some researchers have made efforts generate electromagnetic (EM) radiation by driving magnetization ferri-/ferro-magnetic materials, which can be efficiently realized via mechanical stress in strain-mediated multiferroics. However, very little done accurately model coupling elastodynamics...
In this work, we present a detailed leakage current study on arrays of GaAs p-n junction nanopillars grown by MOCVD.[1-2] Nanopillar/nanowire-based photovoltaics are actively examined as highly efficient solar absorbers. To achieve highly-performing devices, however, methodical understanding the nature currents is needed.[3] Reducing key to improve diode characteristic and open-circuit voltage under light, especially. This work considers matrix 5 × different patterned geometries where...
