Computation of Physical Optics Integral by Levin’s Integration Algorithm
In this paper, a novel algorithm for computing Physical Optics (PO) integrals is introduced. In this method, the integration problem is converted to an inverse problem by Levin’s integration algorithm. Furthermore, the singularities, that are possible to occur in the applications of Levin’s method, are handled by employing trapezoidal rule together with Levin’s method. Finally, the computationa...
متن کاملAn Efficient Method for Computing Highly Oscillatory Physical Optics Integral
Abstract—In this work, we use the numerical steepest descent path (numerical SDP) method in complex analysis theory to calculate the highly oscillatory physical optics (PO) integral with quadratic phase and amplitude variations on the triangular patch. The Stokes’ phenomenon will occur due to various asymptotic behaviors on different domains. The stationary phase point contributions are careful...

15 صفحه اولComputation of Trigonometric Functions by the Systolic Implementation of the CORDIC Algorithm
Trigonometric functions are among the most useful functions in the digital signal processing applications. The design introduced in this paper computes the trigonometric functions by means of the systolic arrays. The method for computing these functions for an arbitrary angle, , is the CORDIC algorithm. A simple standard cell is used for the systolic array. Due to the fixed inputs, in some...
