Abstract

By definition a Temporal Photonic Crystal TPC is a medium whose permittivity and or permeability is modulated in time periodically The dispersion relation of a TPC exhibits gaps in its wave vector k or propagation constant betha rather than the usual frequency or energy gaps This leads to various interesting phenomena such as reflection and transmission of multiple harmonics by a TPC slab parametric resonances and peculiar pulse transmission While such behavior is difficult to achieve in the optical regime it can be readily realized by radio waves and microwaves propagated in transmission lines In this case it is the capacitance C t and or inductance L t that is periodically modulated I will report the first experimental observation of a k or betha gap harmonics created by the Dynamic Transmission Line and beats in transmitted signals in excellent agreement with theoretical calculations and the corresponding TPC
