Integral equation methods (IEMs) are powerful and widely used for solving various electromagnetic (EM) problems due to their unique features. Compared with differential equation methods (DEMs) like the finite-difference time-domain (FDTD) method and finite element method (FEM), the IEMs do not require the implementation of absorbing boundary condition (ABC) with a perfectly matched layer (PML) and also have a much smaller solution domain which is defined by the surface or volume of objects. Furthermore, the IEMs are very flexible for complicated structures and have a better scaling property for computational costs so that they have been preferred in many applications. The IEMs mainly include the method of moments (MoM) and Nyström method (NM), or their variations. The MoM is an extensively-applied IEM or integral equation solver (IES) owing to its accuracy and stability, but it requires well-designed basis functions defined over conforming meshes and evaluation of double integrations for generating matrix elements. The NM has become a very robust IES in recent years and could be a strong competitor with the MoM. The merits of NM include the simple mechanism of implementation, removal of basis and testing functions, ease of achieving a higher accuracy, and use of nonconforming meshes, but it requires an efficient treatment for singularities in integral kernels. We shall review the two IEMs and their applications for solving real-world challenging EM problems. In particular, we will introduce our work on them in recent years and highlight their robustness on solving complicated EM problems.
