wave equation

n
(General Physics) physics a partial differential equation describing wave motion. It has the form ∇2φ = (1/c2) × (∂2φ/∂t2), where ∇2 is the Laplace operator, t the time, c the speed of propagation, and φ is a function characterizing the displacement of the wave

0], the excitation frequency f = 1GHz, and I = 1mA, the exact solution may be obtained by solving the wave equation in the spectral domain as presented in Appendix A.
A model for sound wave propagation in a room with heterogeneous medium, for example, a screen in the room leads to more or less efficient method for solving the wave equation, for example using the Boundary Element Method (BEM) and finds an approximate solution to the wave equation by solving the system of equations resulting from discretizing the surfaces into patches.
Note that in this setting it is, of course, much simpler to calculate the wave function directly by solving the wave equation with numerically with finite elements.
