High-frequency homogenization for periodic media
An asymptotic procedure based upon a two-scale approach is developed for wave propagation in a doubly periodic inhomogeneous medium with a characteristic length scale of microstructure far less than that of the macrostructure. In periodic media, there are frequencies for which standing waves, periodic with the period or double period of the cell, on the microscale emerge. These frequencies do n...
متن کاملHomogenization in random media and effective medium theory for high frequency waves
We consider the homogenization of the wave equation with high frequency initial conditions propagating in a medium with highly oscillatory random coefficients. By appropriate mixing assumptions on the random medium, we obtain an error estimate between the exact wave solution and the homogenized wave solution in the energy norm. This allows us to consider the limiting behavior of the energy dens...
متن کاملDynamic homogenization in periodic fibre reinforced media. Quasi-static limit for SH waves
The effective response of a periodic fibre reinforced material to SH wave propagation is studied using the method of asymptotic homogenization, complex variable theory and multipole expansions. The quasi-static limit of the effective properties is calculated when the wavelength is much longer than the defining lengthscale of the microstructure. The method developed allows the determination of t...
متن کاملFrom periodic travelling waves to travelling fronts in the spike-diffuse-spike model of dendritic waves.
In the vertebrate brain excitatory synaptic contacts typically occur on the tiny evaginations of neuron dendritic surface known as dendritic spines. There is clear evidence that spine heads are endowed with voltage-dependent excitable channels and that action potentials invade spines. Computational models are being increasingly used to gain insight into the functional significance of a spine wi...
متن کاملRecent computational methods for high frequency waves in heterogeneous media
In this note, we review our recent results on the Eulerian computation of high frequency waves in heterogeneous media. We cover three recent methods: the moment method, the level set method, and the computational methods for interface problems in high frequency waves. These approaches are all based on high frequency asymptotic limits.
