Abstract: |
We consider localized instantaneous sources that reside in a 2D diffusive environment. Our goal is to reconstruct the induced field, which turns to be completely determined by a finite number of the source parameters. Although the field is bandlimited, we propose a method for its perfect reconstruction. Three different setup scenarios are discussed. The example of heat diffusion is particularly considered and one solution of the practical realization is proposed. Simulation results confirm applicability of the method. |
