Multiband fractal cross dipole frequency selective surface
多频段十字分形频率选择表面

Fractal structures has self-similar properties so that they can be applied in the field of frequency selective surface(FSS) as unit cell and the fractal FSS has the nature of simple,multi-band characteristics on single layer FSS which can be used as spatial pass filters for the incident angle,polarization and the frequency of the electromagnetic wave.Take fractal cross dipole as example,which we can obtain by recursive algorithm and iterative technique,this work gives the expressions of the fractal elements...
