The solenoidal basis functions defined on tetrahedrons are modified to permit the analysis of the problem of scattering of electromagnetic waves by inhomogeneous dielectric objects. In the analysis of the scattering of EM plane waves by an inhomogeneous dielectric cube, we compare our results with those obtained using pulse basis functions. We also apply our method in the analysis of the scattering of EM plane waves by an inhomogeneous dielectric sphere, and compare the results with those obtained using the Mie's series. Finally, we apply our method in the analysis of the electromagnetic fields induced inside human tissue. We compare these results with those obtained using pulse basis functions. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 23: 42–46, 1999.
