Field Equations in the Complex Quaternion Spaces [PDF]

open access: yes, 2014
The paper aims to adopt the complex quaternion and octonion to formulate the field equations for electromagnetic and gravitational fields. Applying the octonionic representation enables one single definition to combine some physics contents of two fields,

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.

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.
