Explicit Formulas for Solutions Of Maxwell’s Equations in Conducting Media

, 2020
A new explicit presentation of the fundamental solution of the time-dependent Maxwell’s equations in conducting isotropic media is derived by Hadamard techniques through the fundamental solution of the telegraph operator.

Principal modes of Maxwell’s equations

, 2018
This chapter reviews the use of principal modes—states which are maximally correlated between two subspaces and hence form pairs unique up to phase factors—in solving Maxwell’s equations and analysing these solutions for nanoparticles and structures. The

Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

Advanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

Analytical solutions of 1D Maxwell’s equations via infinite-order expansions

Results in Applied Mathematics
Analytical solutions to Maxwell’s equations are essential for understanding the causal and instantaneous behavior of electromagnetic fields, yet they are challenging to obtain in open-space settings with general initial values and source terms. This work

Development of discontinuous Galerkin methods for Maxwell’s equations in metamaterials and perfectly matched layers

, 2011
The discontinuous Galerkin method has proved to be an accurate and efficient way to numerically solve many differential equations. In this paper, we extend this method to solve the time-dependent Maxwell’s equations when metamaterials and perfectly ...

Dyons and Certain Symmetries in Maxwell’s Equations

, 2017
We developed certain symmetries in Maxwell’s equations by incorporating (independent) dynamical degrees of freedom. Once magnetic monopoles are included, it was assessed whether this system can admit electromagnetic-like scalar and pseudo-scalar fields ...

Charged participants and their electromagnetic fields in an expanding fluid

Physics Letters B
We investigate the space-time dependence of electromagnetic fields produced by charged participants in an expanding fluid. To address this problem, we need to solve the Maxwell's equations coupled to the hydrodynamics conservation equation, specifically ...
