The Chebyshev approximation technique (CAT) combined with the MoM based on electric-field integral equation (EFIE) and Poggio–Miller–Chang–Harrington–Wu–Tsai (PMCHWT) is proposed to efficiently calculate wide-band radar cross-section (RCS) passive bistatic radars (PBR). EFIE-PMCHWT equations can be used analyze electromagnetic scattering of coated targets. combination CAT only requires computin...

This paper presents the adaptive integral method (AIM) utilized to solve scattering problem of mixed dielectric/conducting objects. The scattering problem is formulated using the Poggio-MillerChang-Harrington-Wu-Tsai (PMCHWT) formulation and the electric field integral equation approach for the dielectric and conducting bodies, respectively. The integral equations solved using these approaches ...

[1] Tsai and Li [2008] assert that the Bayesian information criterion (BIC) [Schwarz, 1978] is better suited for comparing models having different parameters than is the Kashyap criterion (KIC) [Kashyap, 1982] because a Fisher information term in the latter may rank models with relatively large parameter estimation uncertainties higher than other models. We start by noting that KIC reduces asym...

Density matrices of graphs are combinatorial laplacians normalized to have trace one (Braunstein et al. Phys. Rev. A, 73:1, 012320 (2006)). This work deals with properties of density matrices of graphs and indicates some venues for future research in this subject. Namely, we prove that the condition called degree-criterion, which was conjectured to be necessary and sufficient for separability o...

Composite materials are popular in aerospace engineering because of their light weight, high strength to weight ratio, stiffness to weight ratio and tailoring properties. However, the modeling of composites is still a challenging task because of its highly uncertain material properties which arise from the manufacturing process.The effect of material uncertainties in failure strength and reliab...
