Abstract :
We propose a model to numerically evaluate the transient optical field in the case of magnetic super-resolution (MSR). The method can be extended to optical data storage systems involving transient effects. This model has potential application in identifying the role played by different parameters in the switching process and the optical signal and thus in their optimization.
