Acoustic

Acoustic type and functions.

MultipleScattering.Acoustic — Type.

Acoustic{T<:AbstractFloat,Dim}(ρ::T, c::Complex{T})
Acoustic(ρ::T, c::Union{T,Complex{AbstractFloat}}, Dim::Integer)

Physical properties for a homogenous isotropic acoustic medium with wavespeed (c) and density (ρ)

Simulations in this medium produce scalar (1D) fields in Dim dimensions.

MultipleScattering.check_material — Method.

check_material(p::Particle{T}, outer_medium::Acoustic{T})

Checks if wave scattering from the particle p is physically viable given the material properties of p and its surrounding medium outer_medium.
