(General Physics)physicsa partial differential equation describing wave motion. It has the form ∇2φ = (1/c2) × (∂2φ/∂t2), where ∇2is the Laplace operator,tthe time,cthe speed of propagation, and φ is a function characterizing the displacement of the wave ...
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 existence of traveling waves in strongly inhomogeneous media is reviewed in the framework of the one-dimensional linear wave equation with a variable speed. Such solutions are found by using a homogenization, in which the variable-coefficient wave equation is transformed to a constant-coefficient...
