Equation [6] is known as theWave EquationIt is actually 3 equations, since we have an x-, y- and z- component for theEfield. To break down and understand Equation [6], let's imagine we have an E-field that exists in source-free region. Suppose we only have an E-field that is ...
The linearized wave equation was developed in Chapter 3 on the basis that the fluid element considered was not subject to any external force, did not receive or lose heat or fluid mass, and suffered no intrusion through the action of external agents. The solutions of the equation therefore ...
We focus on the finite integration technique for the spatial discretization of the first-order wave equation systems using lowest order elements. A universal framework of staggered grids is set up in which the application of the finite integration technique for acoustics, electromagnetics and ...
Bessel beams, which are solutions of the free-space Helmholtz equation, exhibit unique transverse amplitude distributions that can be described by the Bessel functions of the first kind. These beams possess remarkable properties, including non-diffraction and self-reconstruction, and can feature an extr...
This description above of in-and out-waves is almost identical to the quantum waves of the electron obtained rigorously using a scalar wave equation in Section D below. Thus we can deduce that the partial success of Wheeler and Feynman method was due to switching of the wave type during the...

We develop a controllability strategy for the computation of frequency-domain solutions of the 3D visco-elastic wave equation, in the perspective of seismic imaging applications. We generalize the controllability results for such equations beyond the sound-soft scattering (obstacle) problem. We detail ...
