| Abstract: | Abstract A general method is presented for designing spherically symmetric gradient-index axicons, which produce a variety of different intensity patterns along the axis, and with a boundary index larger than or equal to the index of the surrounding medium. As the design method is based on geometrical optics, tools to analyse the axicon using wave optics are given. |
