Abstract: Coupled ferrite and dielectric image guides with nonreciprocal behavior in Ka-band (26–38 GHz) have been investigated experimentally with the help of electric probes. The ferrite element has been magnetized inhomogeneously by a disk-shaped permanent magnet. The distributions of all three electric field components in forward and backward direction of propagation have been measured along the coupling length. Examination of measured distributions permit to clarify the operating mechanism of the nonreciprocal ferrite-dielectric structure. This structure can be used for design of nonreciprocal devices, namely isolators for this part of millimeter wave range.
