title: Resonance suppression in the extinction spectrum of single and aggregated hemispheres on a reflecting surface.
abstract: The extinction spectrum from single and aggregated hemispheres whose flat faces lie on a reflecting surface is calculated, and some of the expected resonances are found to disappear for specific choices of the direction and the polarization of the incident wave. This resonance-suppressing effect is fully explained for the case of single hemispheres, whereas for the case of aggregated hemispheres the guidelines for its explanation are given.
