Research and Markets has included John Wiley and Sons’ new book titled ‘Nanostructured and Subwavelength Waveguides. Fundamentals and Applications’ to its catalogue.
Optical waveguides are essential components in photonics as they can confine and transmit light effectively between an excitation point and a detection point. In addition, waveguides enable control over the basic properties of light and facilitate highly controlled interplay with other optical systems. These capabilities allow the widespread adoption of waveguides in high power light delivery, light sources, spectroscopy, sensing and telecommunications.
Subwavelength and nanostructured waveguides demonstrate additional benefits. They can trap light at a length scale lower than the diffraction limit, suppress or improve light-matter interaction, and control basic light properties such as phase propagation, direction of energy and speed.
This book covers semi-analytical hypothesis and practical applications of several nanostructured and subwavelength optical waveguides and fibers that operate in terahertz, mid-infrared, near-infrared, and visible regions of the electromagnetic spectrum. Numerous approximate and highly accurate analytical expressions are obtained that demonstrate different modal properties of the circular and planar metamaterials, anisotropic and isotropic fibers and waveguides, and surface waves passing through on circular and planar interfaces. Different natural and synthetic materials are also taken into account such as metals, dielectrics, anisotropic metal-dielectric metamaterials, all-dielectric metamaterials, and polar materials.
Key topics covered in the book include Introduction; Hamiltonian Formulation of Maxwell Equations for the Modes of Anisotropic Waveguides; Wave Propagation in Planar Anisotropic Multilayers, Transfer Matrix Formulation; SlabWaveguides Made from Isotropic Dielectric Materials. Example of Subwavelength Planar Waveguides; SlabWaveguides Made from Anisotropic Dielectrics; Metamaterials in the Form of All-Dielectric Planar Multilayers; Planar Waveguides Containing All-Dielectric Metamaterials; Circular Fibres Made of Isotropic Materials; Circular Fibres Made of Anisotropic Materials; Metamaterials in the Form of a Periodic Lattice of Inclusions; Circular Fibres Made of All-Dielectric Metamaterials; Modes at the Interface between Two Materials; Modes of a Metal Slab Waveguide; Modes of a Metal Slot Waveguide; Extended Waves in the Infinite Metal/Dielectric Periodic Multilayers (Long-Wavelength Limit); Examples of Applications of Metal/Dielectric Metamaterials; Modes of MetallicWires, Guidance in the UV&ndash near-IR, Mid-IR and Far-IR Spectral Ranges; and Semianalytical Methods of Solving Nonlinear Equations of Two Variables.
