In addition to the propagation constant, the characteristic impedance also affects the scattering characteristics because that the reflection coefficient relates to the impedance mismatch. 13, the stop-band regions exhibit reactive impedance, which is inductive or capacitive one; thus, the incident energy is reflected back to the input region. Furthermore, we have carried out the scattering analysis for the 1D periodic structure composed of conventional dielectric material and a DNG medium. 14.
2 Transformation between space- and eigen-coordinate systems 26 Periodic Structures 3. negative permittivity and negative permeability; 4. positive permittivity and negative permeability. 48). 65) The first medium is a commonly used medium. The second medium is a plasma medium able to be found in nature. For instance, a noble metal in visible light exhibits the plasma effect. Contrarily, the third and fourth mediums have, so far, not been found in nature, but can be synthesized using traditionally used metallic and dielectric materials.
2 Will Surface Waves be Supported in a Single Interface Environment? 19. 19 A single interface between two semi-infinite mediums guided wave along the interface? In the following, we will discuss this problem based on the transverse resonance technique described previously. First of all, we assume that the permittivity and permeability of the dielectric medium are κεo and μo , respectively, where κ is the relative dielectric constant. 132) and kt is the propagation constant along the transverse plane, which is continuous across the two media.
