Abstract :
This contribution presents a rigorous method to obtain the eigenmodes of canonical conducting objects. The inner-product definition is used and the dyadic Green´s function is expanded by vector wave functions. The expressions for the eigenvalues and normalized eigencurrents of a circular sphere are revisited and used as a benchmark. Numerical errors due to the high frequency and low frequency limitations are discussed.
