Abstract

In this work, we provide experimental and theoretical evidence of negative group delays (NGDs) for pulses reflected on symmetric, linear, and passive microstrip slabs and distributed Bragg reflectors (DBRs) through frequency- and timedomain characterization. These microwave operating devices excellently scale to their analogous structures in the optical range, and confirm recent theoretical predictions on weakly absorbing dielectric slabs. In this context, we demonstrate a simple scaling law for the group delay at the slab's design frequency. In the case of DBRs, we show that, as opposed to transmitted pulses, NGDs do occur for pulses reflected in these linear and periodical one-dimensional (1D) structures. This result sheds light into the still controversial question as whether negative tunneling times are possible in 1D photonic crystals.
