摘要：
A modified Luneburg lens based on Hamiltonian optical transformation with planar feeds is proposed in this Letter. The lens, made of conventional all-dielectric materials, does not have any kind of anisotropy. Therefore, in theory, its bandwidth of operation has no upper frequency limitations in contrast with recent designs utilizing metamaterials. Results for wide-angle radiation and broadband operation are presented. (C) 2012 Optical Society of America
