Three dimensional pictures for Thom's parabolic umbilic
Waves of excitations in heterogeneous annular region II. Strong asymmetry
Excitation wave propagation in a heterogeneous medium around a circular obstacle is investigated, when the obstacle is located very eccentrically with respect to the interfacial circle separating the slow inner and the fast outer region. Qualitative properties of the permanent wave fronts are described, and the calculated wave forms are presented.
