| To calculate electromagnetic field propagation we want to solve Maxwell's equations that link electric and magnetic field components and its time and space evolution. The basic idea being FDTD technique is a succesive update of electric and magnetic field components that are specially placed in the computational volume as shown on the following image: | To calculate electromagnetic field propagation we want to solve Maxwell's equations that link electric and magnetic field components and its time and space evolution.

| For update of any component we need only surrounding field values which makes the method suitable for parallelization. | For update of any component we need only surrounding field values which makes the method suitable for parallelization. | ||
