Bound states in the continuum and long-lived electronic resonances in two-tangent loops cavity Open
Bound states in the continuum (BICs) has emerged as a significant research focus in electronics due to its exceptionally high quality factor (Q-factor). BICs (known also as trapped modes) are not observable from the spectrum due to their n…

Physics of surface vibrational resonances: pillared phononic crystals, metamaterials, and metasurfaces Open
The introduction of engineered resonance phenomena on surfaces has opened a new frontier in surface science and technology. Pillared phononic crystals, metamaterials, and metasurfaces are an emerging class of artificial structured media, f…

Closed loop examples Open
The specific properties of closed loop eigenfunctions deserve to be better understood. This chapter underlines that responses in closed loops differ from the responses in open loops. Within the following simple examples, constructed on clo…

Fibonacci loop structures: bandgaps, power law, scaling law, confined and surface modes Open
We study theoretically and experimentally the existence and behavior of scaling law, power law, as well as confined and surface modes in one-dimensional (1D) quasiperiodic photonic bandgap structures. These structures are made of segments …

One-dimensional photonic waveguide for filtering and demultiplexing Open
In this chapter, we review numerical simulations of light propagation in one-dimensional photonic semiconductor optical waveguides coupled to one or several lateral stubs. In the presence of one stub, we show that the transmission spectrum…

Transmission line photonic crystals: a comparison of Green's formalism, lumped circuit element model, and finite element method Open
This chapter presents the modeling, using Advanced Design System (ADS) from Keysight Technologies and Finite Element Method (FEM) based on Comsol Multiphysics tools, of photonic circuits. We particularly report in this chapter a confirmati…

View article: Omnidirectional bandgaps and selective transmission in layered photonic crystals
Omnidirectional bandgaps and selective transmission in layered photonic crystals Open
It has been shown that a one-dimensional periodic structure such as a layered photonic crystal can exhibit the property of omnidirectional reflection, which means that any incident wave launched from the vacuum (or from a substrate) will u…
View article: Closed loop
Closed loop Open
A closed loop can be obtained by linear superposition of the two free ends of an open loop. Its main property is the double degeneracy of its states. The analytical expressions of its eigenvalues, eigenfunctions, and response function are …

Interface response function in layered photonic materials Open
The interface response theory was presented for any composite material in discrete, continuous, and mixed (partly discrete – partly continuous) spaces (see Chapter 1 of Phononics in Interface Transmission Tutorial Book Series). The aim of …

Closed loop and stubs Open
Closed loops with finite open loops attached to the robust zeros of one of their two twin states are the systems investigated in this chapter. Such attached finite loops are called stubs. For simplicity, here only the cases where all the s…

Multilayered structures based one dimensional photonic crystals for MEMS applications Open
This chapter presents and discusses the modeling of multilayered structures based 1D photonic crystals for micro-electro-mechanical systems (MEMS) applications. We particularly report in this chapter a design for realizing a 1D photonic cr…

Eigenfunction rules Open
It is well known that eigenfunctions have to be continuous at each space point of the structure in which they are localized. This is not the only rule they have to fulfill. Rules involving eigenfunction derivatives are also used in the bul…

Path states Open
Any open and closed loop eigenfunction has zero motion space points, called here robust zeros. Any such zero is robust because its eigenstate cannot be activated by any action applied on it. Indeed, such zero space positions remain unaffec…

Open loop examples Open
The simplest general robust zero is the middle of an open loop. When the middles of several free-end open loops of the same length are superposed, their antisymmetric eigenfunctions remain unperturbed and the final network has several dege…

Electromagnetic induced transparency, induced absorption, and Fano resonances in photonic circuits Open
In this chapter, a simple photonic device consisting of two dangling side resonators grafted at two sites (U-shape) or at the same site (cross-shape) along a waveguide is designed in order to obtain sharp resonant states inside the transmi…
