Abstract: The invention concerns a monitoring method that comprises coupling in an integral manner at least one electromagnetic mirror of passive type with a given target to be monitored and monitoring the given target; wherein monitoring the given target includes: acquiring, via one or more synthetic aperture radar(s) installed on board one or more satellites and/or one or more aerial platforms, SAR images of a given area of the earth's surface where the given target is located; and determining, via a processing unit, a movement of the electromagnetic mirror on the basis of the acquired SAR images.

Abstract: A computer-aided FEM-based structure design system is provided that operates to: acquire an initial structure design configuration comprising: a design domain (?), an applied load (f), and constrained, unconstrained and loaded areas (?D, ?F, ?N); compute an initial mesh (Th0) of the design domain (?); compute a topologically optimized structure model by iterating, until a termination criterion is fulfilled: computing an optimized structure topology by properly implementing the SIMP (Solid Isotropic Material with Penalization) algorithm based on a density function (?) that represents the distribution of the material in the structure; computing an anisotropic recovery-based a posteriori error estimator (?) that quantifies the error between the gradient of the exact structure material density (?) and the gradient of the FEM-computed approximation thereof, computing a metric (Mk+1) for anisotropic mesh adaptation based on the anisotropic recovery-based a posteriori error estimator (?), and computing an ada
