This paper presents the design of a non-magnetic optical cloak based on coordinate transformation. Unlike previous cloaking methods that rely on magnetic materials, this approach uses a non-magnetic structure to achieve invisibility at optical frequencies. The cloak is designed to render a macroscopic object invisible by manipulating electromagnetic waves through a cylindrical shell with specific anisotropic permittivity and permeability distributions. The key idea is to compress a cylindrical region using a coordinate transformation, which results in specific requirements for the material properties of the cloak. The cloak's performance is verified using full-wave finite-element simulations. The design avoids the need for optical magnetism by focusing on TM polarization, which allows the use of conventional dielectrics and reduces the complexity of the structure. The cloak is constructed using metal wires embedded in a dielectric material, with the radial permittivity distribution achieved through a composite structure. The effective permittivity of the composite material is calculated using an effective-medium theory, which allows for the design of the cloak with minimal imaginary part in the permittivity, reducing losses. The design is validated through simulations showing that the cloak can effectively guide electromagnetic waves around the hidden object, with minimal scattering. The cloak operates at a wavelength of 632.8 nm, using silver and silica materials. The results demonstrate that the cloak can achieve a high level of invisibility, although some losses are unavoidable due to the material properties and the nature of the cloaking mechanism. The proposed design is generalizable to other cloaking structures and can be applied to various frequency ranges, including infrared and microwave. The study highlights the potential of non-magnetic optical cloaks in achieving invisibility and opens new avenues for the development of cloaking devices at optical frequencies.This paper presents the design of a non-magnetic optical cloak based on coordinate transformation.
