Abstract
Finite-Difference Time-Domain (FDTD) method is playing an important role in solving the Maxwell equation because the FDTD algorithm is a relatively fast method. While the simplicity is definitely another reason why the FDTD was used widely, the FDTD is also able to solve extremely complicated engineering problems.
For the situation of typical electric dipole transition, the maximum scattering cross section of the subwavelength nanoparticle can be proved to be 3λ^2/2π. This limit from standard scattering theory was named the single channel limit.
In this report, we will apply FDTD method to implement several simulations and investigate the relationship between the response and the single channel limit.
