WebMay 22, 2024 · Maxwell’s equations are differential equations, and as with most differential equations, their solution is obtained with particular boundary conditions that here are imposed by conductors. Electric conductors (i.e., electric walls) support electric charges and hence electric current. WebIn this chapter we introduce Maxwell's equations in the time and frequency domains, examine the representation of fields by the Lorenz and Debye potentials, and look at the boundary conditions that fields need to satisfy across material interfaces and at infinity.
