WebNov 30, 2003 · This book covers four major topics of integrated photonics: 1) fundamental principles of electromagnetic theory; 2) waveguides; 3) simulation of waveguide modes, and 4) photonic structures. The first part of the text explores the basis for optical propagation and establishes the use of the MKS system, discussing the wave equation and the … WebIn this paper a slab of stacked near cut-off rectangular waveguides emulating an ε-near-zero (ENZ) artificial material is designed to behave as a bi-concave symmetric lens. First, a rectangular narrow hollow waveguide is simulated in order to show how such device can be used to mimic an ENZ medium. albero della vita logo

WebMar 4, 2005 · A physical realization of scattering by -symmetric potentials is provided: we show that the Maxwell equations, for an electromagnetic wave travelling along a planar slab waveguide filled with gain and absorbing media in contiguous regions, can be approximated in a parameter range by a Schrodinger equation with a -symmetric scattering potential. WebFeb 21, 2024 · Because they are simple to design and make, half-wave dipole antennas are very common. In fact, almost all antennas are based on this design, which has clean, linear polarization and a rotationally symmetric radiation pattern. A half-wave dipole antenna consists of a linear conductive element of length L = l/2, typically fed by means of a gap ...
