On the Efficient and Accurate Application of Partial Differential Equation Solvers of Maxwell's Equations in the Time Domain (1992)A new field/voltage relation for use with the symmetric condensed node transmission line matrix (TLM) method is introduced. It is found that there is no rigorous mathematical proof which demonstrates the consistency and ...
(1994)Radiative transfer theory is used to model the multiple scattering of diffuse ultrasonic waves in two types of random media. The first type is an isotropic, homogeneous medium containing randomly oriented, randomly located ...
(1990)In Fourier synthesis, natural musical sounds are produced by summing time-varying sinusoids. Sounds are analyzed to find the amplitude and frequency characteristics for their sinusoids; interpolation between the characteristics ...
(1995)Scattering from an imperfect planar interface between two different elastic media was studied to examine how the signals induced at the transducers by reflected, transmitted and scattered waves are related to the interface ...
(1992)The methods presented in this thesis were developed to study the electron propagation in nanostructures with special emphasis on semiconducting materials. The essence of nanometer-scale physics is in the phase coherence ...
