Abstract
An analytical solution is derived for a singular integral equation which governs some twodimensional potential boundary value problems in a region exterior to n‐infinite co‐axial circular strips. An application in electrostatics is discussed.
Highlights
In this paper we derive a solution to the Fredhoim singular integral equation where q and a are constants and I"(0)is a differentiable nction for ]0- (2k# n)l < a,k 0 n-I This integral equation governs the solution of various two-dimensional Difichlit and Neumann potential bounda value problems for the region consisting of the whole (r, O) plane outside the circular strips
The previous investigations in potential problems of circular strips [1,2,3,4,5,6,7,8] were concerned mainly with the case of two strips,where Greens nction approach leads to a singular integral equation with kernel sin(O-) q + log
A different technique has been used by Sampath and Jain [4] based on decoupling the equation into two singular equations which can be solved using eigennctions expansion metod The same technique has been used to solve various bounda value problems involving two circular strips[ 5-8
