About the Authors Christophe Bourlier works at the IETR Institut d Electronique et de T l communications de Rennes laboratory at Polytech Nantes University of Nantes, France as well as being a Researcher at the French National Center for Scientific Research CNRS on electromagnetic wave scattering from rough surfaces and objects for remote sensing applications and radar signatures

Appendix

Chapter 3 presents numerical results, obtained from the MoM, of the coherent and incoherent intensities scattered by a random rough surface and an object below a random rough surface

Contents 1

Gildas Kubick is in charge of the Expertise in electroMagnetism and Computation EMC laboratory at the DGA Direction G n rale de l Armement , French Ministry of Defense, where he works in the field of radar signatures and electromagnetic stealth

He is the author of more than 160 journal articles and conference papers

His research interests are in the areas of radar and optical remote sensing, scattering and propagation

His research interests include electromagnetic scattering and radar cross-section modeling.

In Chapter 1, the MoM is applied to convert the IEs into a linear system, while Chapter 2 compares the MoM with the exact solution of the field scattered by a cylinder in free space, and with the Physical Optics PO approximation for the scattering from a plate in free space

In particular, he works on asymptotic methods of electromagnetic wave scattering from random rough surfaces and layers

In these last two chapters, the coupling between the two scatterers is also studied in detail by inverting the impedance matrix by blocks

In this book, the Method of Moments MoM is applied to compute the field scattered by scatterers such as canonical objects cylinder or plate or a randomly rough surface, and also by an object above or below a random rough surface

Integral Equations for a Single Scatterer Method of Moments and Rough Surfaces

Matlab Codes

Nicolas Pinel is currently working as a Research Engineer at the IETR laboratory at Polytech Nantes and is about to join Alyotech Technologies in Rennes, France

Scattering from Two Illuminated Scatterers

Scattering from Two Scatterers Where Only One is Illuminated

Since the problem is considered to be 2D, the integral equations IEs are scalar and only the TE transverse electric and TM transverse magnetic polarizations are addressed no cross-polarizations occur

The final chapter presents the same results as in Chapter 3, but for an object above a random rough surface
