The electronic transmission properties and the energy spectrum of a mesosco
pic necklace with inhomogeneons flux is calculated. We found interesting tr
ansmission behavior that is quite different from the case with homogenous f
lux. In this model, the transmission depends on both the modulation mode an
d the amplitude of the flux. The electronic transmission properties can be
explained from the energy-spectrum of the system. [S1063-651X(99)05904-8].
