N2 - In this letter, we present composite linear spatial transformation to design a rotatable illusion device, which can generate various illusion effects on antenna radiation pattern hinging upon the location of the radiation source. For the radiation element placed on the boundary of the external region, the electromagnetic field distribution is rotated and compressed in the meanwhile. The radiation element located in the region covering compression zone and extension zone, the radiation pattern is altered, an omnidirectional radiation is transformed into a directive one and deflected with a certain angle. Furthermore, the radiation source contained in the compression zone is virtually moved to the space outside of the illusion device and rotated a certain angle as defined simultaneously. Full wave numerical simulations using Finite Element Method have been performed to demonstrate these properties.
