An analytical method known for phase filters is applied to amplitude filters. The method is based on the use of a series of figures of merit, such as the axial and the transverse gains and the Strehl ratio, which characterize the point-spread-function distribution near the focal region. As a practic

A new approach to die shape optimal design in shape extrusion is presented. In this approach, the design problem is formulated as an optimization problem incorporating the three-dimensional finite element analysis model, and optimization of the die shape is conducted on the basis of the design sensi
## Abstract This Letter presents a fast solution to the electricβfield integral equation (EFIE) for large, threeβdimensional, arbitrarily shaped objects. The EFIE is discretized by the method of moments and the precorrectedβFFT method is then used to accelerate the matrixβvector multiplications in
