Several surface integral formulations for electromagnetic interactions with homogeneous material bodies are studied numerically. Included are the well-known Müller and PMCHWT formulations and two previously unreported formulations. One of the two formulations introduced gives a simple form of the Neumann series for low-contrast material bodies. The integral formulations are discretized to matrix equations using the method of moments. The condition numbers of the matrices are evaluated using several definitions of norms. Number of iterations in CG method is also presented for each formulation.
