Total photoionization cross section of planar helium: scaling laws and collision orbits (2018)
Journal Article

The total photoionization cross section of planar helium has been calculated up to the single ionization threshold I22 of triple P states. The cross section shows chaotic fluctuations as the energy E approaches the double ionization threshold E=0. By...

Near-field scanning and propagation of correlated low-frequency radiated emissions (2017)
Journal Article

Electromagnetic radiation from complex printed circuit boards can occur over a broad frequency bandwidth, ranging from hundreds of MHz to tens of GHz. This is becoming a critical issue for assessment of EMC and interoperability as electronic componen...

Wigner-Function-Based Propagation of Stochastic Field Emissions from Planar Electromagnetic Sources (2017)
Journal Article

© 1964-2012 IEEE. Modeling the electromagnetic radiation from modern digital systems - acting effectively as extended stochastic sources as part of a complex architecture - is a challenging task.

Journal Article

We report a new planar antenna design in the shape of a diamond.

Improved approximation of phase-space densities on triangulated domains using discrete flow mapping with p-refinement (2017)
Journal Article

We consider the approximation of the phase-space flow of a dynamical system on a triangulated surface using an approach known as Discrete Flow Mapping. Such flows are of interest throughout statistical mechanics, but the focus here is on flows arisin...

Transport of phase space densities through tetrahedral meshes using discrete flow mapping (2016)
Journal Article

Discrete flow mapping was recently introduced as an efficient ray based method determin- ing wave energy distributions in complex built up structures.

A phase-space approach for propagating field–field correlation functions (2015)
Journal Article

We show that radiation from complex and inherently random but correlated wave sources can be modelled efficiently by using an approach based on the Wigner distribution function.

Journal Article

A series of quantum search algorithms have been proposed recently providing an algebraic speedup compared to classical search algorithms from N to \sqrt{N}, where N is the number of items in the search space.

A boundary integral formalism for stochastic ray tracing in billiards (2014)
Journal Article

Determining the flow of rays or non-interacting particles driven by a force or velocity field is fundamental to modelling many physical processes.

Journal Article

We propose a reformulation of the boundary integral equations for the Helmholtz equation in a domain in terms of incoming and outgoing boundary waves. We obtain transfer operator descriptions which are exact and thus incorporate features such as diff... Read More about In–out decomposition of boundary integral equations.

Journal Article

We study implications of unitarity for pseudo-orbit expansions of the spectral determinants of quantum maps and quantum graphs.
