J. Carbonell et al., ELECTRIC-FIELD PATTERNS IN FINITE 2-DIMENSIONAL WIRE PHOTONIC LATTICES, Superlattices and microstructures, 22(4), 1997, pp. 597-605
Electric field patterns in finite two-dimensional wire photonics latti
ces are investigated by means of electromagnetic simulations. These st
udies reveal a strong analogy with the envelope wavefunction approach
extensively used for semiconductor superlattices. Several propagating
eigenmodes in the pass-band of the periodic structure as well as evane
scent modes in the stop-bands are clearly identified. They are interpr
eted on the basis of the matching of the wavelength of electromagnetic
field to the lattice dimensions with an envelope wavefunction resulti
ng of a Fabry-Perot effect in the cavity formed by the periodic struct
ure. In terms of transmission coefficient, the calculated frequency de
pendence are in agreement with those measured in finite metallic rod a
rrays between 50 and 110 GHz. (C) 1997 Academic Press Limited.
