Strictly conformal transformation optics for directivity enhancement and unidirectional cloaking of a cylindrical wire antenna [PDF]
Scientific Reports, 2022 Using conformal transformation optics, a cylindrical shell made of an isotropic refractive index material is designed to improve the directivity of a wire antenna while making it unidirectionally invisible.

Hybridization of singular plasmons via transformation optics [PDF]
Proc Natl Acad Sci U S A, 2018 Significance Surface plasmons, which are optical resonances supported by metallic nanostructures, are extremely useful for manipulating light on the nanoscale. However, designing novel plasmonic devices becomes quite challenging when the desired spectral

Transformation optics for perfect two-dimensional non-magnetic all-mode waveguide couplers
Optical Materials Express, 2019 Here, we demonstrate that transformation optics can be used to produce 2-D non-magnetic waveguide couplers with no reflections. Our approach consists of using a scaling function for reflection suppression and introducing an auxiliary function in the ...
