NGnet-Based Topology Optimization of a 1-Bit Reconfigurable Intelligent Surface (RIS) Unit Cell
This paper presents a topology optimization approach for the design of a 1-bit reconfigurable intelligent surface (RIS) unit cell based on a Normalized Gaussian Network (NGnet) combined with Particle Swarm Optimization (PSO). The unit cell operates in the 2.4 GHz Wi-Fi band and employs a single PIN diode to realize two...
