Condition 1:

A 2D infinite plane and there is a circular hole in the middle. When t=0, an impulsive loading, P=f(t), is applied to the boundary of the circle(outward), so the wave will start at the boundary of the circle and propagate in the plane

Condition 2:

A 3D infinite plane and there is a circular hole in the middle. When t=0, an impulsive loading, P=f(t), is applied to the boundary of the sphere(outward), so the wave will start at the boundary of the sphere and propagate in space

During the wave propagation in the plane, assuming there is dissipation (actually I don't know what caused it, thermal maybe, but I think in the world, waves cannot travel endlessly, and I only need to know from the geometry perspective). How to model the energy dissipated regarding the geometry? Basically, the modeling for the energy dissipated during 2D propagation in a plane and 3D spherical propagation?

Thanks
