In this work we investigate the complex magnetic and electric dipolar resonances of a subwavelength gallium arsenide (GaAs) prolate spheroid.
We employ a formulation based on spheroidal vector wave functions (VWFs) for the expansion of the electromagnetic fields in the interior and exterior of the spheroid. Satisfying the boundary conditions at the spheroidal surface, we finally obtain a linear system of equations. The resonance wavelengths are obtained by setting the system's determinant equal to zero and utilizing an efficient root-finding algorithm.
Comparisons with HFSS commercial software are performed, and numerical results are given for different aspect ratio nanospheroids.
