“…Much less is understood about PQC confinement for accelerators, with no selfconsistent theory to calculate the optimal dielectric arrangement. The first numerical simulations to achieve accelerating mode confinement in an irregular structure were carried out by (Bauer et al, 2008) with subsequent investigations of PQCs by (DiGennaro et al, 2009). The concept of a band gap does not apply to these aperiodic structures, yet their special arrangement of dielectric elements can in some cases provide stronger confinement than finite PBG structures with the same number of elements.…”

The use of infrared lasers to power optical-scale lithographically fabricated particle accelerators is a developing area of research that has garnered increasing interest in recent years. We review the physics and technology of this approach, which we refer to as dielectric laser acceleration (DLA). In the DLA scheme operating at typical laser pulse lengths of 0.1 to 1 ps, the laser damage fluences for robust dielectric materials correspond to peak surface electric fields in the GV/m regime. The corresponding accelerating field enhancement represents a potential reduction in active length of the accelerator between 1 and 2 orders of magnitude. Power sources for DLA-based accelerators (lasers) are less costly than microwave sources (klystrons) for equivalent average power levels due to wider availability and private sector investment. Due to the high laser-to-particle coupling efficiency, required pulse energies are consistent with tabletop microJoule class lasers. Combined with the very high (MHz) repetition rates these lasers can provide, the DLA approach appears promising for a variety of applications, including future high energy physics colliders, compact light sources, and portable medical scanners and radiative therapy machines.

The interest to the SC PCs is due to their applications in a new type of resonators 34 and microstrip filters based on YBa 2 Cu 3 O 7 which work in the gigahertz regime. 35 By tuning the temperature of the superconductor, the RI of the SC component can be changed, and as a consequence, the PBG can be controlled.…”

The influence of the variation in the incidence angle on the photonic band gap spectra of a one-dimensional dielectric photonic crystal with a complex defect layer, consisting of ultrathin superconducting and dielectric sublayers, was theoretically investigated. The behavior of the defect modes with different polarizations as a function of the incidence angle variation is studied numerically for different thicknesses of the superconducting sublayer. The pronounced contrast in behavior of TE-and TM-polarized modes was demonstrated. The intensity of the TE-polarized defect mode decreases with increasing incidence angle, whereas the intensity of the TM-polarized defect mode increases. The increase in the superconducting defect sublayer thickness leads to a shift in the defect mode of TM-polarization to higher frequencies.

In this chapter, we review the salient results of our recent investigations on in-plane wave propagation in photonic quasi-crystals. Via full-wave numerical simulations and microwave measurements, we illustrate the band-gap, mode confinement, and focusing properties of twodimensional structures made of dielectric or metallic cylindrical rods arranged according to diverse aperiodic-tiling geometries.Selected Topics in Photonic Crystals and Metamaterials Downloaded from www.worldscientific.com by SOUTHERN TAIWAN UNIVERSITY OF SCIENCE AND TECHNOLOGY on 08/12/15.
