Transformation optics offers remarkable control over electromagnetic fields and has recently opened an exciting gateway to design field rotator devices.We propose a distributed field rotator with open windows based on composite transformation optics,which consists of a central circular region and several isolated components.The number,position and size of the components can be controlled freely by the design purpose.Full-wave simulations are performed to demonstrate its function,which is equivalent to a classic field rotator.However,such a distributed rotator makes it much easier to access and make use of the rotated field in the central ragion,compared to the closed classic field rotator,especially in the case of 3D situations.
