Abstract :
To broaden the bandwidth of one-way waveguide, we study possible ways to increase the bandwidth of one-way edge states of magnetic photonic crystal. We find broadband one-way waveguide can be realized by merging the frequency range of topological edge states and magnetic surface plasmon (MSP) resonance caused one-way edge states. The merged frequency range could be up to 3.2 GHz in microwave regime, much larger than that of based on the topological or MSP one-way edge states only.
