Photonic band gap (PBG) dielectric fibers with hollow cores are being studied both theoretically and experimentally for use as laser driven accelerator structures. The hollow core functions as both a longitudinal waveguide for the transverse-magnetic (TM) accelerating fields and a channel for the charged particles. The dielectric surrounding the core is permeated by a periodic array o... https://www.spidertattooz.com/Beckett-s-27-Coconut-Rum-Non-Alcoholic-Spirit-375ml/
