A novel method to realize zero phase delay of electromagnetic wave

摘要：

　　Zero phase delay of electromagnetic wave (EMW) transmission can be realized based on the wavefront modulation of photonic crystals (PhCs).When the phase velocity is controlled perpendicular to the group velocity with wavefronts (or phasefronts) parallel to the direction of energy flow,the phase will keep constant in transmission process despite of the increase of propagating length.The phase different between the incident and transmitted waves is measured to demonstrate that the phase can remain invariable in PhCs instead of zero-index materials or zero-averaged-index PhC superlattices.This effect can be extended to other artificially engineered materials,and will open a new route to obtain perfect zero-phase-delay propagation for EMW.
