Fast algorithm and surface integral equations for two-dimensional materials modeling
… achieved with a multi-level scheme. Then a metasurface platform to generate structured light at second harmonics is proposed with transition metal dichalcogenide (TMDC) flakes. With the aid of the electric field integral equation and impedance boundary condition, the surface currents on TMDC …

Studies of some issues in solving surface integral equations and the equivalence principle algorithm
… with the formulation for the electric field integral equation (EFIE), and visit the necessary treatment of the magnetic field integral equation (MFIE), the combined field integral equation (CFIE), and the Poggio-Miller-Chu-Harrington- Wu-Tsai (PMCHWT) along with various singularity extraction …

Accuracy improvement of the second-kind Fredholm integral equations in computational electromagnetics
… electromagnetics, the second-kind Fredholm integral equations (IEs) are known to have very fast iterative convergence but rather poor solution accuracy compared with the first-kind Fredholm integral equations. The loss of the numerical accuracy is mainly due to the discretization error of …

Fast algorithms for solving integral equations of electromagnetic wave scattering
… solving two-dimensional and three-dimensional integral equations of electromagnetic wave scattering. They include: (1) The fast iterative method, which reduces the matrix-vector multiplication from $N\sp2$ to $N\sp{1.5}$ and to N (log(N) $\sp2.$ (2) A fast far-field approximation (FAFFA) …

A surface integral equation method for dielectrics at low frequencies
This thesis is dedicated to using surface integral equations to solve electro- magnetic problems involved in integrated circuits. Since normally the sizes of the devices in this application are much smaller than the wavelength of the electromagnetic waves, special considerations are needed because …

Electromagnetic analysis with discrete exterior calculus
… for both partial differential equation (PDE) and integral equation (IE) based approaches. A systematical treatment is proposed for various boundary conditions. With a careful implementation of the Hodge star operators, we are able to represent and solve electromagnetic PDEs properly with DEC. And …
