Abstract :
The simulated performance for novel hexagonal FCL circulators is presented for the first time. Compared to conventional FCL circulators, these structures do not require external biasing and have the advantages of smaller size and lower conductor and dielectric loss. Simulations show that the size decreases as the value of 4πMeff of the hexaferrite increases.
