The advantages afforded by the symmetrical C(V) characteristics of Heterostructure Barrier Varactor (HBV) diodes for the fabrication of nonlinear metamaterials are investigated numerically. The studies are conducted by means of full‐wave numerical modelling along with circuit analysis. It is believed that the HBV technologies can replace the conventional Schottky diode not only in up and down frequency conversion left‐handed devices, but also by bringing new functionality in terms of space filtering for unbiased devices. © 2007 Wiley Periodicals, Inc.
