Surface Configuration Design of Cable-Network Reflectors Considering the Radiation Pattern
TL;DR: In this paper, the authors investigated the effect of the geometric approximation errors of the curve surface of a cable-network reflector on the electromagnetic performance of the reflector and proposed three new surface configurations.

Topology optimization of pretensioned reflector antennas with unified cable-bar model
TL;DR: To determine the layout of the prestressed cables, a gradient-based topology optimization model was established and a parameter control strategy for the sigmoid functions is carried out during the optimization procedure.

Novel Worst-Case Surface Accuracy Evaluation Method and Its Application in Reflector Antenna Structure Design
TL;DR: Both quantitative analysis and numerical example of a 110 m radio telescope show that this method can improve the worst-case accuracy effectively, and based on the analysis, this method is sub-optimal.
Iteration Path-Length Error Correction Approach to Subreflector Shaping for Distortion Compensation of Large Reflector Antenna
TL;DR: In this article, a method performing an iterative approximation to the geometrical optics and physical optics analysis is proposed to shape a subreflector for antenna distortion compensation, which is very suitable for a large reflector antenna with a small-amplitude deformation and smoothly varying errors.

Calculation of the Best Fit Subreflector and Its Application in Eliminating the Harmless Error of Deformed Large Subreflectors
TL;DR: In this article, the authors proposed seven parameters to determine the best fit subreflector (BFS): five rigid parameters (three translation and two rotation parameters) and two parameters related to the change of the sub reflector shape.
