Let’s consider a thin slab of metal, which the electromagnetic wave falls on. An angle of falling we will designate as θ. Let’s assume that a vector of electric ﬁeld of the electromagnetic wave is parallel to a slab surface. Such wave is called s–wave (see  or ). We take the Cartesian system of coordinates with the origin of coor-. The resonance reflection of a plane electromagnetic wave from a diffraction grating consisting of wide-spaced, thin, tilted metal strips is confirmed and investigated experimentally. Good agreement is obtained between the experimental results and published theoretical : S. N. Vorob’ev, I. K. Kuzmichev. In terms of transmission, the magnetic field created by the outgoing current is almost exactly canceled by the field from the return current, so electromagnetic waves are only weakly induced. In reception, both conductors are bathed in the same electric and magnetic fields, so an emf that adds current on one side subtracts current from the. Reflection of Electromagnetic Waves. The impedance for electromagnetic waves is defined as the ratio between the voltage and current waves, where are inductance and capacitance per unit length in medium. For example, the inductance, capacitance, and impedance of a coaxial cable is given by where a and b are the inner and outer radii of the.
Abstract: This paper presents a novel way of constructing waveguiding structures by stacking several thin metal plates for millimeter-wave and terahertz applications. The metallic layers do not require any electrical contacts among them. An air-filled multi-layer waveguide (MLW) transmission line is successfully designed and manufactured at by: 2. The ability to control the local response of electromagnetic wave through subwavelength thickness has provided a promising platform for many novel applications, such as negative refractive index.
