Abstract
The coupling effects between the surface plasmons on metal nanostructures and the radiating dipoles in the quantum wells of a light-emitting diode have been observed. In this thesis, an accurate computation of the electromagnetic field distribution is necessary for understanding the physical mechanisms of the coupling effects. We develop a program which is based on a boundary integral equation method to solve the multiple-objects scattering problem. For testing the accuracy of our program, we make calculation for some special cases and compare the numerical results with the analytical solutions obtained by Mie theory. Then we calculate the electromagnetic field and the scatterd power of a radiating dipole near multiple metal nanospheres. Numerical results reveal that our method is useful for investigating the coupling effects between radiating dipoles and nearby metal nanospheres.
