Abstract

Electromagnetic mode profile shaping would be a very useful technique, with applications including in accelerator science and data transmission. Two methods are proposed, one varying the permittivity, the other using a wire medium. By the use of Mathieu functions we demonstrate a flatter, a triangular and a peakier profile. The first two may be used to manipulate longer particle bunches, while the last could be used on shorter bunches and in data transmission. It is also demonstrated how further improvements can be achieved by going beyond Mathieu functions.
