The electromagnetic energy stored inside a cylinder, which is irradiated by an electromagnetic plane wave, is calculated analytically. In view of their differing energy density functions, dispersive and nondispersive cylinders are treated separately. Numerical results show that the stored energy exhibits resonant enhancement near the extinction resonances of the cylinder. An application to the calculation of the transport velocity in a two-dimensional disordered medium is presented.
