Field calculation in single- and multilayer coaxial cylindrical shells of infinite length by using a coupled T- Omega and boundary element method

A method is presented for the calculation of the electromagnetic field in systems of single-layer or multilayer coaxial cylindrical shells of infinite length excited by an oscillating current source arbitrarily oriented inside the first shell. The electric vector potential T and the magnetic scalar potential Omega are used for the evaluation of the quantities of the problem. The Helmholtz equations for T and Omega are transformed into integral equations by the use of the Green's function method. Applying the boundary element method, three systems of simultaneous equations have to be solved to give the sought field quantity.<
