\u8b1b\u6f14\u8005:Prof. Kamal Sarabandi (University of Michigan, U.S.A)<\/p>\n
\u6982\u8981\uff1aThe problem of electromagnetic (EM) wave propagation in random
\nmedia composed of a heterogeneous mixture of different scattering
\nparticles in a background medium is encountered in many practical
\napplications.
\nScattering and propagation of light through fog or murky water are
\nfamiliar examples of such problems. The scattering and absorption by
\nthe particles are responsible for the wave attenuation and the
\nscattering alone is responsible the wave phase front aberration and
\nthe field spatial fluctuation. The scattering phenomenon becomes
\nimportant as the size of the constituent particles become comparable
\nor larger than the wavelength. In this talk we consider the problem of
\nEM wave propagation and scattering in rain at millimeter-wave (MMW)
\npart of the spectrum because of its importance in radar remote sensing
\nof precipitation as well as the emerging MMW 5G and 6G communication
\nand the use of MMW radars for autonomous vehicles. The analysis of EM
\nwave interaction with rain as a random medium is important since at
\nMMW band, the size of the rain particles are comparable to the
\nwavelength which can result in considerable scattering. Knowing the
\nspecific statistical characteristics of wave propagation such the
\nattenuation rate through rain enables more accurate link budget
\nplanning for communication and radar systems. Also information about
\nthe statistics of the phase and amplitude fluctuations of the waves in
\nrain enables better performance analyses of antenna arrays used in
\ncommunication and radar systems.
\nAnalytical models based on single scattering theory are inadequate for
\nthe prediction of long range wave propagation characteristics in such
\nmedia, as the effect of multiple scattering among particles become
\nimportant. To account for the effects of multiple scattering a
\nfull-wave simulation must be considered which is quite challenging
\nconsidering the size of the computational domain. Considering the fact
\nthat the statistical nature of the wave propagation properties, as
\nopposed to exact field quantities for a specific medium configuration,
\nis of desire, a novel computational model based on S-matrix is
\ndeveloped. The attributes of the S-matrix method are as follows: 1) it
\nis based on full-wave analysis, 2) it is applicable to dense or sparse
\nrandom media,
\n3) it tracks the polarization of the wave along the propagation, 4) it
\ntracks phase aberration to the phase front needed for assessing the
\nperformance of coherent imaging systems such as SAR or MIMO radar
\noperating in random media, 5) it can be used for any random media with
\narbitrary shaped scatters. In the presentation, the formulation for
\nthe S-matrix method and its application for predicting the attenuation
\nrate and wave fluctuation statistics will be presented. The model is
\nvalidated by comparing the simulation results with the existing
\nattenuation rate measurements reported in the literature.
