Abstract :
This paper demonstrates the possibility of designing a fully planar slotline isolator based on magnetized semiconductor substrates at room temperature. Semiconductors magnetized with dc magnetic bias can be used to overcome some of the limitations of ferrites. The design is based on the non-reciprocal field displacement effect, and is intended for the V and W frequency bands. Two configurations will be proposed and then accessed using 2D (eigenvalue) and 3D finite element based simulations
