Transformation optics allows conventional lenses and antennas to better fit their
environment. A planar profile Cooke Triplet is found by FDTD simulation to behave as well as
the conventional Cooke Triplet. An all-dielectric device design is used so the device is broadband
and has acceptable loss levels. The transformation designed triplet has better directivity than
the conventional design.
