中文摘要: The feasibility of 360aˆˆ˜ scanning Luneburg lens based on electric-controlled metamaterial is analyzed. When the line source is fixed in the center of the lens, the direction of radiated beam can be tuned by adjusting the bias voltages distribution applied to the varactors in each unit cell. By introducing an artificial reflective plane, the gain of the antenna can be further enhanced. The minimal step of scanning angle obtained in simulation is only 7aˆˆ˜, which can be further decreased by increasing the dimension and the number of unit cell used in Luneburg lens. © 2013 Springer-Verlag Berlin Heidelberg.
