| Abstract: | The propagation modes in the lenslike medium, including the spot size, field distribution pattern and their propagation constant,are obtained by solving the Helmholtz equation in the cylindrical coordinate. The coupling coefficients between the incident laser and those propagation modes are derived and discussed. |
