N2 - We show how to control the field profile on a sub-wavelength scale using a customised permittivity variation in a functional medium, thus avoiding the need to e.g. synthesize the shape from its Fourier harmonics. For applications such as beam dynamics, requiring field profile shaping in free space, we show that it is possible to achieve this despite using a slot in the medium.
