Abstract :
The emission of a radiating source is virtually delocalized through the use of transformation electromagnetics concept. The electromagnetic device able to perform such a transformation is obtained by a space compression followed by a space expansion. Moreover, the radiation pattern of the virtual source can be modified such that an omnidirectional radiation can be changed into a directive one. Theoretical formulations are presented and full wave numerical simulations are performed to present the approach.
