A canonical problem in electromagnetic backscattering from buildings

G. Franceschetti; A. Iodice; D. Riccio IEEE Transactions on Geoscience and Remote Sensing, 2002

In this paper, a geometric and electromagnetic model of a typical element of urban structure is presented, in order to analytically evaluate in closed form its electromagnetic return to an active microwave sensor. This model can be used to understand what information on geometric and dielectric properties of a building can be extracted from microwave remote sensing data. The geometrical ...

In this paper, introduced is an application of two radiometric slope correction methods on standard RADARSAT images in a mountainous environment like the Alps. Because of the highly varying topography, such corrections are needed to reduce the distortions on the backscattering coefficients when trying to monitor the snow characteristics from SAR data in alpine regions.

The paper investigates digital elevation model (DEM) generation based on data from the ultra wideband coherent all radio band sensing (CARABAS) very high frequency (VRF)-band synthetic aperture radar (SAR). The results show excellent capability to penetrate forest areas, i.e., the generated DEMs are found to be close to the true ground height. A conventional DEM, based on stereo photography and ...


High-frequency backscattering from a singly curved screen

  • Characterization Techniques for Film Characteristics

    This chapter shows data regarding whisker phenomena that are characterized by the most recent transmission electron microscopy (TEM), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) techniques. It introduces several examples of SEM image use in tin whisker analysis: observation of tin whisker shape, measurement of tin whisker length and kink angle, and confirmation that tin whiskers do indeed generate from the base metal. The chapter describes concrete examples of whisker analysis that use the techniques. The chapter also discusses general crystal orientation characterization techniques and then focuses on the principles of and advances in EBSD and its use in investigating the effects of crystal orientation on tin whisker formation. Many examples of characterization by using TEM, SEM, and EBSD techniques for tin and tin???based alloy finishes show how to clarify the essential characteristics of the films so that the authors can deepen their understanding of whisker formation mechanisms.

  • Index

    **Discusses the growth mechanisms of tin whiskers and the effective mitigation strategies necessary to reduce whisker growth risks** This book covers key tin whisker topics, ranging from fundamental science to practical mitigation strategies. The text begins with a review of the characteristic properties of local microstructures around whisker and hillock grains to identify why these particular grains and locations become predisposed to forming whiskers and hillocks. The book discusses the basic properties of tin-based alloy finishes and the effects of various alloying elements on whisker formation, with a focus on potential mechanisms for whisker suppression or enhancement for each element. Tin whisker risk mitigation strategies for each tier of the supply chain for high reliability electronic systems are also described. * Discusses whisker formation factors including surface grain geometry, crystallographic orientation-dependent surface grain boundary structu e, and the localization of elastic strain/strain energy density distribution * Examines how whiskers and hillocks evolve in time through real-time studies of whisker growth with the scanning electron microscope/focused ion beaming milling (SEM/FIB) * Covers characterization methods of tin and tin-based alloy finishes such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) * Reviews theories of mechanically-induced tin whiskers with case studies using pure tin and other lead-free finishes shown to evaluate the pressure-induced tin whiskers _Mitigating Tin Whisker Risks: Theory and Practice _is intended for the broader electronic packaging and manufacturing community including: manufacturing engineers, packaging development engineers, as well as engineers and researchers in high reliability industries.
