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.diegojavierfares.com/hot-deal-Cobra-Fly-XL-Graphite-Mens-Right-Hand-Package-Set-Regular-Fly-XL-save-more/
