a Optical image of the taper region of the AB-type four-stage topological beamformer. Simulated b transmission and c phase of a single taper of the AB-type four-stage topological beamformer as a function of frequency and length L of the rectangular bar of the taper coupler. The transmission remains constant, while the phase undergoes a 2π variation across the entire bandwidth.
