We present a three dimensional (3D) metamaterial that behaves as a lowpass, bandpass or stopband filter, depending on the polarization and direction of propagation of the incident plane wave. The metamaterial unit cell was designed exclusively using circuit theory and nanocircuit lumped element concepts, without requiring the initial use of wave concepts and/or numerical wave simulations, thus demonstrating the useful potential offered by this approach in the design of complex optical metamaterials.
