Investigation of Illusion Optics Devices Implemented by Transmission-line Metamaterials with Full Tensors
With the proposition of transformation optics,there emerged a lot of novel electromagnetic devices such as the invisibility cloaks,field concentrators,illusion optics devices and so on,which provide a unconventional functions for arbitrarily control the behaviors of electromagnetic waves.The practical implementation of such devices must take use of metamaterials(MTMs)for that the devices needs anisotropic and non-uniform medium parameters.As a candidate of MTMs with wideband and low loss properties,periodic transmission line(TL)networks were widely used to mimic MTMs with unique characteristics.However,the effective medium parameters possessed by TL MTMs before are all diagonal in the Cartesian basis,which limit the development of MTMs with more complex parameters.Recently,a group in the University of Michigan proposed a new structure of TL MTMs with arbitrary full tensors,in other words it can achieve any 2D anisotropic and non-uniform materials.In this paper,this kind of tensor TL metamaterials was introduced to the field of illusion optics invisibility system.Two circuit simulations are presented,one is an illusion optics system which optically transforms one object to another and the other is a rectangle invisibility cloak that cloaks objects at a distance outside the cloaking shell.Its found that TL MTMs with full tensors can be well applied to mimic transformation optics devices with complex medium parameters distributions.
