This review focuses on the optical properties and device applications of deterministic
aperiodic media generated by mathematical rules with spectral features that interpolate in a …

In this work we consider the role of aperiodic order—order without periodicity—in the design
of different optical devices in one, two and three dimensions. To this end, we will first study …

In many resonant structures the damping of parasitic or higher order modes is indispensable
to guarantee a correct and stable performance. This is particularly true in the microwave …

In order to understand the performance of photonic band-gap (PBG) structures under
realistic high gradient, high power, high repetition rate operation, a PBG accelerator …

We present results for a photonic microwave resonator designed and fabricated at 17.4 GHz
with a record high Quality factor (Q= 26,400) at room temperature over a mode volume …

Resistive-wall impedance constitutes a significant percentage of the total beam-coupling
impedance budget of an accelerator. A number of different reduction techniques have been …

This paper reports the first high power tests of hybrid photonic band gap (PBG) accelerator
structures. Three hybrid PBG (HPBG) structures were designed, built and tested at 17.14 …

We report on the formation and development of the photonic band gap in two-dimensional 8-
, 10-, and 12-fold symmetry quasicrystalline lattices of low-index contrast. Finite-size …

In a recent investigation, we studied two-dimensional (2D) point-defected photonic bandgap
cavities composed of dielectric rods arranged according to various representative periodic …

Wakefield excitation has been experimentally studied in a three-cell X-band standing wave
photonic band gap (PBG) accelerating structure. Major monopole (TM 01-and TM 02-like) …
