Comment on "Characterization of an acoustic spherical cloak", Inverse Problems 31(3):035001, 2015
The paper [1] considers a spherical cloak described by three radially varying acoustical quantities. For a given radial mass density in the cloak the question posed is whether the remaining two…

Classical Zero-Point Radiation and Relativity: The Problem of Atomic Collapse Revisited
The physicists of the early 20th century were unaware of two aspects which are vital to understanding some aspects of modern physics within classical theory. The two aspects are: 1) the presence of…

Quasi-Hamiltonian description of classical spin
A family of Lagrange functions is considered, each producing the classical relativistic free spinning particle equation of motion of the third order. On this grounds a generalized…

Planck-Einstein-de Broglie relations for wave packet: the acoustic world
In this paper we study the relations of Planck-Einstein-de Broglie type for the wave packets. We assume that the wave packet is a possible model of particle . When studying the behaviour of the wave…

Auxetic-like metamaterials as novel earthquake protections
We propose that wave propagation through a class of mechanical metamaterials opens unprecedented avenues in seismic wave protection based on spectral properties of auxetic-like metamaterials. The…

A Novel Visualization of the Geometry of Special Relativity
The mathematical treatment and graphical representation of Special Relativity (SR) are well established, yet carry deep implications that remain hard to visualize. This paper presents a new graphical…

Objective thermomechanics
An irreversible thermodynamical theory of solids is presented where the kinematic quantities are defined in an automatically objective way. Namely, auxiliary elements like reference frame, reference…

Twisting Somersault
A complete description of twisting somersaults is given using a reduction to a time-dependent Euler equation for non-rigid body dynamics. The central idea is that after reduction the twisting motion…

Generalized Transformation Design: metrics, speeds, and diffusion
We show that a unified and maximally generalized approach to spatial transformation design is possible, one that encompasses all second order waves, rays, and diffusion processes in anisotropic…

Strong limitations on allowable gauge transformations in electrodynamics
Conservation principles establish the primacy of potentials over fields in electrodynamics, both classical and quantum. The contrary conclusion that fields are primary is based on the Newtonian…

Universal Dielectric Enhancement from Externally Induced Double Layer Without ζ-Potential
Motivated by recent experiments showing over 104-fold increase in induced polarization from electrochemically inert, conducting materials in dilute saline solutions, we theoretically demonstrate a…

Asymmetric acoustic propagation of wave packets via the self-demodulation effect
This article presents the experimental characterization of nonreciprocal elastic wave transmission in a single-mode elastic waveguide. This asymmetric system is obtained by coupling a selection layer…

The maximum force in a column under constant speed compression
Dynamic buckling of an elastic column under compression at constant speed is investigated assuming the first-mode buckling. Two cases are considered: (i) an imperfect column (Hoff's statement),…

An Extra Electrostatic Energy in Semiconductors and its Impact in Nanostructures
This work revisits the classical concept of electric energy and suggests that the common definition is likely to generate large errors when dealing with nanostructures. For instance, deriving the…

Dynamical pressure for fluid mixtures with several temperatures
We consider binary mixtures of fluids with components having different temperatures. A new dynamical pressure term is associated with the difference of temperatures between components even if fluid…

Four ways to justify temporal memory operators in the lossy wave equation
Attenuation of ultrasound often follows near power laws which cannot be modeled with conventional viscous or relaxation wave equations. The same is often the case for shear wave propagation in tissue…
