Title
An Introduction to the Locally Corrected Nystrm Method (Synthesis Lectures on Computational Electromagnetics),Used
Delivery time: 8-12 business days (International)
This lecture provides a tutorial introduction to the Nystrm and locallycorrected Nystrm methods when used for the numerical solutions of the common integral equations of twodimensional electromagnetic fields. These equations exhibit kernel singularities that complicate their numerical solution. Classical and generalized Gaussian quadrature rules are reviewed. The traditional Nystrm method is summarized, and applied to the magnetic field equation for illustration. To obtain high order accuracy in the numerical results, the locallycorrected Nystrm method is developed and applied to both the electric field and magnetic field equations. In the presence of target edges, where current or charge density singularities occur, the method must be extended through the use of appropriate singular basis functions and special quadrature rules. This extension is also described.
