AN Improved UTD Based Model For The Multiple Building Diffraction Of Plane Waves In Urban Environments By Using Higher Order Diffraction Coeficients
This paper describes an improved model for multiple building diffraction modeling based on the uniform theory of diffraction (UTD). A well-known problem in conventional uniform theory of diffraction (CUTD) is multiple-edge transition zone diffraction. Here, higher order diffracted fields are used in order to improve the result; hence, we use higher order diffraction coefficients to improve a hy...
متن کاملExtracting UTD Wedge Diffraction Coefficients from Electric Field Measurements
The geometrical theory of diffraction (GTD) provides a powerful and computationally efficient framework for investigating real-world diffraction problems. Originally restricted to perfectly electrically conducting (PEC) wedges, the GTD and its uniform offspring have since been extended to wedges characterized by impedance surfaces (R. Tiberio et al., IEEE Trans. AP, 37, 2, 212-218, 1989). Thoug...

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...
A Para1netri.e Formulation of the UTD Diffraction Coefficients for a Dielectric Wedget
Appropriate formulation of the UTD diffracted field is important for propagation prediction. Among the wedge. diffraction solutions for nonperfectly conducting surfaces in the literature, exact formulations are mostly based on Maliuzhinets's derivation [1] and are computationally prohibitive for practical applications. On the other hand, heuristic formulations, modified from the UTD diffraction...
