We study the interaction of electromagnetic waves with two nested parallel metallic wire arrays, such that the unit cell of the structure has two inequivalent parallel wires. We develop a formalism to solve scattering problems using effective medium methods and prove that the electromagnetic coupling of the two sets of wires may result in the emergence of sharp Fano resonances.
