The transport properties of electromagnetic waves in disordered, finite, two-dimensional photonic crystals composed of circular cylinders are considered. Transport parameters such as the transport and scattering mean free paths and the transport velocity are calculated, for the case where...

Inference of chemical reaction networks based on concentration profiles using an optimization framework.

Chaos (Woodbury, N.Y.)

Langary D, Nikoloski Z.
PMID: 31779367
Chaos. 2019 Nov;29(11):113121. doi: 10.1063/1.5120598.

Understanding the structure of reaction networks along with the underlying kinetics that lead to particular concentration readouts of the participating components is the first step toward optimization and control of (bio-)chemical processes. Yet, solutions to the problem of inferring...

Photonic crystal devices modelled as grating stacks: matrix generalizations of thin film optics.

Optics express

Botten L, White T, de Sterke C, McPhedran R, Asatryan A, Langtry T.
PMID: 19474985
Opt Express. 2004 Apr 19;12(8):1592-604. doi: 10.1364/opex.12.001592.

A rigorous semi-analytic approach to the modelling of coupling, guiding and propagation in complex microstructures embedded in two-dimensional photonic crystals is presented. The method, which is based on Bloch mode expansions and generalized Fresnel coefficients, is shown to be...

Conductance of photons in disordered photonic crystals.

Physical review. E, Statistical, nonlinear, and soft matter physics

Asatryan AA, Botten LC, Byrne MA, Langtry TN, Nicorovici NA, McPhedran RC, de Sterke CM, Robinson PA.
PMID: 15903621
Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Mar;71(3):036623. doi: 10.1103/PhysRevE.71.036623. Epub 2005 Mar 28.

The conductance of photons in two-dimensional disordered photonic crystals is calculated using an exact multipole-plane wave method that includes all multiple scattering processes. Conductance fluctuations, the universal nature of which has been established for electrons in the diffusive regime,...

Bloch mode scattering matrix methods for modeling extended photonic crystal structures. I. Theory.

Physical review. E, Statistical, nonlinear, and soft matter physics

Botten LC, White TP, Asatryan AA, Langtry TN, de Sterke CM, McPhedran RC.

We present a rigorous Bloch mode scattering matrix method for modeling two-dimensional photonic crystal structures and discuss the formal properties of the formulation. Reciprocity and energy conservation considerations lead to modal orthogonality relations and normalization, both of which are...

We present a semianalytic theory for the properties of two-dimensional photonic crystal waveguides of finite length. For single-mode guides, the transmission spectrum and field intensity can be accurately described by a simple two-parameter model. Analogies are drawn with Fabry-Perot...
