Achieving Perfect Imaging beyond Passive and Active Obstacles by a Transformed Bilayer Lens
Wei Yan, Min Yan, Min Qiu
A bilayer lens is proposed based on transformation optics. It is shown that Pendry's perfect lens, perfect bilayer lens made of indefinite media, and the concept of compensated med…
Necessary and sufficient conditions for reflectionless transformation media in an isotropic and homogenous background
Wei Yan, Min Yan, Min Qiu
It has been known that, keeping the outer boundary coordinates intact before and after a coordinate transformation is a sufficient condition for obtaining a reflectionless transfor…
Non-magnetic simplified cylindrical cloak with suppressed zero-th order scattering
Wei Yan, Min Yan, Min Qiu
A new type of simplified cloaks with matched exterior boundaries is proposed. The cloak uses non-magnetic material for the TM polarization and can function with a relatively thin t…
Cylindrical Superlens by a Coordinate Transformation
Min Yan, Wei Yan, Min Qiu
Cylinder-shaped perfect lens deduced from the coordinate transformation method is proposed. The previously reported perfect slab lens is noticed to be a limiting form of the cylind…
