6 Outline Cloaking and Transformation Optics Limitation of Metamaterials with metals at Optical Frequencies Invisibility Carpet Compress object to flat conducting sheet Design using quasi-conformal map A profile of ε>0, µ>0 without extreme values, easier to fabricate and broadband Full wave simulations

9 Avoid Magnetic resonance for cloaking at optical Ag nanowires in Silica Reduced parameter approximation: ( ε, ε, µ ) ( ε µ, ε µ,1) Size of unit cell ~ 100 nm, 632.8nm non-magnetic metamaterials in reduced material parameters θ r θ r TM, reduced parameters W Cai, et. al., Nature Photonics 1, 224 (2007).
10 At optical frequencies Metamaterials (resonating elements) Advantage: large range of material parameters Disadvantage: Elements subwavelength, absorption Dielectrics (far away from resonance) Low absorption, easy to fabricate Broadband: Frequency independent
11 Limitation of Dielectrics Limited anisotropy for fixed permittivities εθ = f ε1 + ( 1 f ) ε 2 1/ ε = f / ε + ( 1 f ) / ε 2.0 r ε 1 ε ε θ ε r ε θ /ε r f Extreme permittivities needed for large anisotropy ε = 0.05, ε = 8 from Y. Huang, et.al., Opt. Exp Extreme values related to the topology of cloak - how we crush an object
12 Three ways to crush an object Crushing an object into a point, a line or a plane 3D Spherical Cloak Singular 2D Cylind. Cloak Singular Carpet Cloak Non-Singular
13 Hiding under a carpet Perceived as a flat ground plane Avoid singular/extreme values for ε and µ h η or ξ 2 virtual system y physical system H y 0 H x ξ or ξ 1 E z Material parameters: µ, ε z w x object to conceal Minimize the anisotropy by an appropriate coordinate transformation

22 Ray tracing Geometrical optics limit
23 Further approximation to ease fabrication Reduced Parameter Approximation (Previous approaches) Need impedance match at outer boundary of cloak ( µ, µ, ε ) ( µ ε, µ ε,1) T L T L Isotropic Approximation (Our approach) Need to have a thicker coating ( µ T, µ L, ε ) ( µ T µ L = 1, µ T µ L = 1, ε )
24 Dielectric Invisibility Carpet n T /n L = α = 1.042, regarded as 1, i.e. µ = 1 ε = n T n L = 0.7 to 2.0, relative to background ε = 1.5 to 4.4 if SiO 2 is the background Cloak can be obtained by drilling holes in Si 1.5 y 1.0 ( ) ε r x y b ( x) ( π x ) 2 0.2cos / 2 1 x 3 = 0 otherwise
25 Cloak at oblique incidence angle Split into two separate beams without cloaking with Cloak E z Object w/o Cloak
