Metamaterials and Cesàro convergence
In this paper, we show that the linear dielectrics and magnetic materials in matter obey a special kind of mathematical property known as Cesàro convergence. Then, we also show that the analytical…

Random scattering by rough surfaces with spatially varying impedance
A method is given for evaluating electromagnetic scattering by an irregular surface with spatially-varying impedance. This uses an operator expansion with respect to impedance variation and allows…

Acoustic versus electromagnetic field theory: scalar, vector, spinor representations and the emergence of acoustic spin
We construct a novel Lagrangian representation of acoustic field theory that describes the local vector properties of longitudinal (curl-free) acoustic fields. In particular, this approach accounts…

Using Nanoresonators with Robust Chaos as HRNGs
In this paper, we investigate theoretically the potential of a nanoelectromechanical suspended beam resonator excited by two-external frequencies as a hardware random number generator (HRNG). This…

Instantaneous Radiation from Time-Varying Electric and Magnetic Dipoles
Radiation from magnetic and electric dipole moments is a key subject in theory of electrodynamics. Although people treat the problem thoroughly in the context of frequency domain, the problem is…

Recovering the normal form of an elasticity tensor
We propose an effective geometrical approach to recover the normal form of a given Elasticity tensor, once we know its symmetry class. In other words, we produce a rotation which brings an Elasticity…

Faster-Than-Light Solitons in 1 + 1 Dimensions
The existence of a faster-than-light particle is in direct opposition to Einstein's relativity and the principle of causality. However, we show that the theory of classical relativistic fields is…

Wave scattering on lattice structures involving array of cracks
Scattering of waves due to a vertical array of equally-spaced cracks on a square lattice is studied. The convenience of Floquet periodicity reduces the study to that of scattering of specific…
