title: Resonance shift of obliquely illuminated dielectric cylinders: geometrical-optics estimates.
abstract: Some characteristics of resonant states in obliquely illuminated cylinders are derived from a geometrical-optics point of view. A formula for the resonance shift that is due to tilted illumination is derived and predictions are compared with data from the literature.
