Area of Science:

  • Electromagnetism
  • Metamaterials
  • Optics

Background:

  • Transformation Optics enables unprecedented control over electromagnetic fields by linking geometry and material properties.
  • Surface-confined waves exhibit a geometrical equivalence between surface shape and refractive index.
  • Conventional singular devices often require infinite refractive indices, posing practical challenges.

Purpose of the Study:

  • To demonstrate that singular devices can be realized for surface-confined waves using sculpted surfaces.
  • To redesign three specific singular omnidirectional devices: Eaton lens, generalized Maxwell Fish-Eye, and invisible sphere.
  • To show these redesigned devices can be implemented with simple isotropic media and low refractive index contrast.

Main Methods:

  • Applying the geometrical equivalence principle for surface-confined waves.
  • Sculpting surfaces to emulate the behavior of singular optical devices.
  • Utilizing low refractive index contrast isotropic media for device fabrication.

Main Results:

  • Successfully redesigned the Eaton lens, generalized Maxwell Fish-Eye, and invisible sphere for surface-confined waves.
  • The redesigned devices perfectly replicate the functionality of their singular counterparts.
  • Achieved these functionalities using simple, low refractive index contrast isotropic materials.

Conclusions:

  • Singular devices, previously requiring infinite refractive indices, can be practically realized for surface-confined waves.
  • Surface sculpting offers a viable pathway to creating advanced optical functionalities with accessible materials.
  • This work simplifies the implementation of complex optical devices, broadening their potential applications.
