ON THE PRINCIPLE OF LIMITING ABSORPTION,
Abstract
In practical problems of electromagnetic theory the sources producing the electromagnetic field have a sinusoidal time dependence. The resulting electromagnetic field is assumed to have this time dependence and the problem becomes a simpler one which is essentially time independent. This method of analysis yields the steady state solution. A para1llel problem concerns the principle of limiting absorption. In practical problems this principle states that if a boundary value problem is solved for a medium which is slightly conducting and then the conductivity is allowed to approach zero, the resaulting limit of the solution is the solution of the same boundary value problem in a non-conducting medium. This principle is important since it is often simpler in the mathematical analysis to introduce an arcificial cooonductivity in order that a solution may be more readily analyzed. (Author)
