Here we demonstrate that an electromagnetic wave scattered at an object carries locally defined and conserved information about all of the object’s constitutive parameters. Specifically, we introduce the density and flux of Fisher information for general types of wave fields and identify the ...

A change in the wave speed will of course lead to a change in the refractive index leading directly to partial reflection of a light wave from a glass plate for example. Similarly, if the wavefield was an acoustic field, and a change in density ρ was introduced, then the acoustic wave ...
Then, the ideal gas law can be rewritten as (γ=cp/cV=1.400 for air at 20°C) (5.56)p=p0(ρρ0)γ Together with the approximation (c0 is the speed of sound at equilibrium density) c=γpρ≈γp0ρ0=c0 the adiabatic ideal gas law simplifies the aeroacoustic wave equation ...

It then becomes natural to also consider the case g(p) = ∂tp, in which case the Lagrange multiplier satisfies a wave equation and the generalised Maxwell's equations become hyperbolic and even strictly hyperbolic if a Lagrange multiplier is also used for the div B constraint. This set of...
