## Abstract The concept of infiniteβphase velocity (IPV) is shown as the boundary between positiveβ and negativeβphase velocities (PPVs and NPVs). As materials displaying PPV and NPV are physically realizable, we conjecture that this applies IPV materials as well. Β© 2004 Wiley Periodicals, Inc. Mic
