Extended Data Fig. 2: Intrinsic broadband topological waveguide phased arrays.
From: On-chip topological beamformer for multi-link terahertz 6G to XG wireless
Simulated a (c) transmission and b (d) phase of the 16 radiating channels of AB- (BA-) type four-stage topological beamformer. The 16 channels of AB- (BA-) type beamformer have similar transmission while showing intrinsic π (0) phase difference between adjacent channels over the entire broad bandwidth of 26.5 GHz (18.9 GHz). e Simulated and measured transmission of BA-type topological beamformers having different numbers of tapers by summing the transmission of all the channels. The shaded gray area of the measured transmission spectrum indicates the standard error.
