Abstract :
Compact expressions are given for the reactive energies and modal quality factors in the literature. The formulas do not involve spherical Bessel functions and are in terms of, at most, two polynomials having positive coefficients which are readily calculable. Curves are presented for the exact forms for a number of modal quality factors.
