摘      要：We present several design examples of how to apply transformation optics and curved space under coordinate transformation to manipulating the surface plasmon waves in a controlled *** demonstrate in detail the design procedure of the plasmonic wave squeezer,in-plane bend and omnidirectional *** show that the approximation method of modifying only the dielectric material of a dielectric-metal surface of the plasmonic device could lead to acceptable performance,which facilitates the fabrication of the *** functionality of the proposed plasmonic device is verified using three-dimensional full-wave electromagnetic *** at practical realization,we also show the design of a plasmonic in-plane bend and omnidirectional absorber by an alternative transformation scheme,which results in a simple device structure with a tapered isotropic dielectric cladding layer on the top of the metal surface that can be fabricated with existing nanotechnology.
