This paper theoretically investigates the reflective properties of splitting and squeezing devices based on a zero-index metamaterial (ZIM) waveguide embedded with defects. This structure can guarantee no reflections, making it possible to build reflectionless splitters and squeezers. Moreover, the proposed theory has been used to couple input and output waveguides with different cross sections and to achieve an arbitrary angle of exotic transmission. The proposed defect structure can offer potential advances in cloaking, splitting, and squeezing technologies without restricting the object’s shape. Active control of exotic transmission can occur by incorporating tunable parameters into the defects and the ZIM
