Abstract
A non-reciprocal mode converting SIW includes a first straight SIW section, a second straight SIW section, and a curved SIW section coupling the first straight SIW section to the second straight SIW section. The curved SIW section included magnetic biasing at opposed corner regions. The magnetic biasing and a curvature of the curved SIW section causes: (i) a wave in a first transverse electric (TE) mode that propagates in a forward direction from the first straight section through the curved SIW section into the second straight SIW section to convert to a second TE mode, and (ii) a wave in the first TE mode that propagates in a reverse direction from the second straight SIW section through the curved SIW section into the first straight SIW section to maintain the first TE mode.
