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 …

Porous silicon has been established as an excellent sensing platform for the optical
detection of hazardous chemicals and biomolecular interactions such as DNA hybridization …

This review focuses on the peculiarities of quasiperiodic order for the properties of photonic
and phononic (sonic) heterostructures. The most beneficial feature of quasiperiodicity is that …

The giant enhancement of multi-band nonreciprocal radiation based on the Weyl semimetal–
dielectric spacer–Thue–Morse multilayer–metallic mirror structure, is investigated. As an …

Porous silicon samples have been reduced in nanometric particles by a well known
industrial mechanical process, the ball grinding in a planetary mill; the process has been …

Quasi-periodic one-dimensional Cantor photonic crystals are elaborated by depositing
alternating silicon and silica Si/SiO 2 layers by radiofrequency magnetron sputtering …

We investigate from a theoretical point of view the photonic properties of a two dimensional
photonic aperiodic crystal. These structures are obtained by removing the lattice points from …

The authors have compared the sensitivities of resonant optical biochemical sensors, based
on both periodic and aperiodic porous silicon structures, such as the Bragg and the Thue …

Even if the first published article on a porous silicon (PSi)-based biosensor dates back to
more than twenty years ago, this technology still attracts great attention from many research …

In this paper, an omnidirectional photonic band gap (OBG) which originates from Bragg gap
compared to zero-n˜ gap or single negative (negative permittivity or negative permeability) …
