Study of Cascaded Black–Quadratic Aperture (CBQA)
摘要
A new Cascaded Black–Quadratic Distribution (CBQD) in circular aperture is suggested. Two different models of CBQD are studied. In the first model, ten strips are considered, where half are black and the other half have a quadratic distribution, starting with a black strip from the center of the circular aperture. In the second model, the annular aperture of the quadratic distribution is considered.
