Intrinsic mode (1M) . parabolic equation (PE) comparisons on radio wave propagation Levent Sevgl and 6zlem Ercan Istanbul Technical University, ElectricalElectronics Engineering Faculty, 80626 Maslak Istanbul Abstract Radiowave propagation In tropospheric ducts near earth's surface Is described In terms of Intrinsic Mode and Parabolic Equation methods, The discussion Is focused on ground wave prop

The influence of antenna aperture and atmospheric absorption on amplitude scintillations on millimetric wave communications links John Haddon Matra Marconi Space UK Ltd, Abbey Works, Tichfield, Fareham, Hants, England Abstract Amplitude scintillations observed on a communication link result from multipath scattering from refractive index fluctuations produced by atmospheric turbulence along the pr

Electromagnetic diffraction computation for a high accuracy direction finder on board a helicopter M Reynaud, A SarremeJean and F Christophe Centre d'Etudes et de Recherche de Toulouse, BP 4025, 31055 Toulouse cedex, France Abstract A comparison between some different theoretical methods for the simulation of electromagnetic scattering phenomena is presented. These methods are used to adjust a syn

A new iterative method for scattering problems M Azlzl, H Aubert and H Baudrand ENSEEIHT, Laboratoire d'Electronique, Groupe Microondes, 2, C Camichel, 31071 Toulouse, France Fax: (33) 61 58 83 77 Abstract A new iterative method for scattering problems is presented. This method is based on the fact that cutoff waves excited by a given source are shunted by pure reactive impedance and we consider t
