✦ Synopsis

A no¨el method combining the conjugate-gradient and ( ) nonuniform fast Fourier transform CG᎐NUFFT algorithms for sol¨ing integral equations in electromagnetics is presented. The CG᎐NUFFT method has been applied to one-and two-dimensional inhomogeneous media. Numerical results show the ad¨antages of the CG᎐NUFFT method o¨er the CG᎐FFT method for problems with both electrically large and small regions.
