Diffraction of Em Plane Wave by a Slit in an Impedance Plane Using Maliuzhinets Function
Diffraction of an electromagnetic plane wave from a slit in an impedance plane has been presented. The method is based on Maliuzhinets technique for impedance surfaces. Comparison of the field patterns with different values of the face impedance are also presented.
متن کاملDiffraction of Plane Waves by a Slit in an Infinite Soft-hard Plane
We have studied the problem of diffraction of plane waves by a finite slit in an infinitely long soft-hard plane. Analysis is based on the Fourier transform, the Wiener-Hopf technique and the method of steepest descent. The boundary value problem is reduced to a matrix Wiener-Hopf equation which is solved by using the factorization of the kernel matrix. The diffracted field, calculated in the f...
متن کاملPhase-shift anomaly caused by subwavelength-scale metal slit or aperture diffraction.
Terahertz time-domain spectroscopy probes anomalous phase-shift caused by wave diffraction from a subwavelength-scale metal slit or aperture. Carrier frequency phase measurements in the far-field region reveals that nearly 30° phase advance is induced from a subwavelength slit diffraction and that 180° phase-advance from a subwavelength aperture. These results indicate that the conventional 90°...
متن کاملLight diffraction by a subwavelength circular aperture
Diffraction of normally incident light by a subwavelength circular aperture is calculated analytically. The aperture is opened on a perfectly conducting planar screen with infinitesimal thickness. In our model, the aperture is replaced by uniform magnetic currents and charges. The model allows one to obtain the normalized cross section for the aperture radius up to half of the wavelength, which...
متن کاملDiffraction of a plane inhomogeneous electromagnetic wave by a perfectly conducting half-plane in an absorbing medium
The Sommerfeld’s problem of plane wave diffraction by a perfectly conducting half-plane is considered for the general case of an absorbing medium and an inhomogeneous incident wave, whose the constant phase planes are not parallel to the constant amplitude ones. The exact solution is represented in terms of parameters of incident wave propagation in the coordinate axes, but not in terms of angu...
