โœฆ Synopsis

Hollow retroreflectors installed on satellites are used as targets for satellite laser ranging and earth-satellite laser long-path absorption measurements. The optical characteristics of a space retroreflector are determined by several parameters, including mirror curvatures, dihedral angles, and the direction of the retroreflector on the satellite. In this paper, we propose using a genetic algorithm to design space retroreflectors. We applied this method for design of a retroreflector 50 cm in diameter. We found that the optimum design of space retroreflectors having high optical efficiency is obtained in a short time by using the genetic algorithm.

## Abstract This paper presents unequal microstrip power divider designs using the hierarchal genetic algorithm (HGA). The dividing ratio and return loss are the design specifications leading the evolution direction. By employing the HGA chromosome formulation, the system structure and its associat
