Abstract :
Imitating waveguide aperture (IWGA) source for FDTD modeling is introduced and studied. IWGA source´s mathematical expression is sufficient approximation of the near field, radiated from the fiber waveguide, in the process of computer simulation of the EM phenomena in PhCs; it could be used as excited source expression by the fiber waveguide
