Dominance of the resonant modes on the internal intensities of a homogeneous spheroidal particle illuminated with a focused, polarized, and shifted Gaussian beam is investigated. The results are calculated for a wider range of size parameter and axial ratio for both prolates and oblates spheroids. The plane wave spectrum and the T-matrix methods are used to calculate the internal electric field intensities. The results show that the resonant modes in an oblate spheroid are more pronounced than in a prolate spheroidal particle. The resonant modes in a spheroidal particle have lower quality factor than those in a spherical particle. The behavior of the internal intensities shows that a high quality factor (loworder) resonant mode(s) can dominate the internal intensities over a wide range of size parameter. This dominance of the resonant modes in a spheroidal particle is larger than those in a spherical particle.
