Abstract:
We investigate the propagation of electromagnetic waves in finite photonic band gap structures. We analyse the phenomenon of conduction and forbidden bands and we show that two regimes are to be distinguished with respect to the existence of a strong field near the interfaces. We precise the domain for which an effective medium theory is sounded.
