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 this study, a combined structure is proposed to develop ultra-thin silicon solar cells. This
integrated structure consists of silver fractal-like nano-particles and leaky wave …

The phase behavior of building blocks with mushroom cap-shaped particle morphology is
explored under 2D and quasi-2D confinement conditions. Fast confocal microscopy imaging …

For dielectric multilayered metamaterials, the effective-parameter representation is known to
be insensitive to geometrical features occurring at deeply subwavelength scales. However …

We present a general and useful method to predict the existence, frequency, and spatial
properties of gap states in photonic (and other) structures with a gapped spectrum. This …

It is common understanding that multilayered dielectric metamaterials, in the regime of
deeply subwavelength layers, are accurately described by simple effective-medium models …

We report experimental results of the reflectance spectra of deterministic aperiodic multilayer
structures fabricated with porous silicon. The refractive index of the layers forming the …

In this work, the theoretical and experimental study on vibration transmission in quasi-
periodic impedance layered structures built by magnetorheological (MR) fluid is conducted …

The propagation of waves in highly inhomogeneous media is a problem of interest in
multiple fields including seismology, acoustics, and electromagnetism. It is also relevant for …

We develop a generalized model for studying second-order parametric interactions in 1-D
multilayered photonic structures, accounting for collinear oblique waves and partial pump …
