Imaging of the equatorial ionosphere

open access: yesAnnals of Geophysics, 2005
The equatorial anomaly is the dominant structure in free electron concentration in the tropical ionosphere. Due to its edges (crests) which are characterised by steep latitudinal gradients in TEC and are temporally and spatially variable, it is

Prediction of radiated electromagnetic emissions from PCB traces based on Green dyadics [PDF]

open access: yes, 1995
Because it costs to solve ElectroMagnetic Compatibility (EMC) problems late in the development process, new methods have to predict radiated electromagnetic emissions at the design stage.

Fourier-Domain Electromagnetic Wave Theory for Layered Metamaterials of Finite Extent [PDF]

open access: yes, 2014
The Floquet-Bloch theorem allows waves in infinite, lossless periodic media to be expressed as a sum of discrete Floquet-Bloch modes, but its validity is challenged under the realistic constraints of loss and finite extent.

Guaranteed passive parameterized model order reduction of the partial element equivalent circuit (PEEC) method [PDF]

open access: yes, 2010
The decrease of IC feature size and the increase of operating frequencies require 3-D electromagnetic methods, such as the partial element equivalent circuit (PEEC) method, for the analysis and design of high-speed circuits.

Rapid Bayesian position reconstruction for gravitational-wave transients [PDF]

open access: yes, 2016
Within the next few years, Advanced LIGO and Virgo should detect gravitational waves from binary neutron star and neutron star-black hole mergers. These sources are also predicted to power a broad array of electromagnetic transients.
