摘要： Disclosed herein are embodiments of low temperature co-fireable dielectric materials which can be used in conjunction with high dielectric materials to form composite structures, in particular for isolators and circulators for radiofrequency components. Embodiments of the low temperature co-fireable dielectric materials can be scheelite or garnet structures, for example barium tungstate. Adhesives and/or glue is not necessary for the formation of the isolators and circulators.

摘要： A nonreciprocal device includes a waveguide through which waves at a first frequency propagate with a first wavevector and with a second wavevector in a direction opposite to the first wavevector; a frequency-dependent device that operates within a frequency range and modifies the waves through the waveguide in a way that is dependent on the first frequency; and a set of couplers to couple the waveguide and the frequency-dependent device. Coupling rates of the set of couplers are modulated to enable nonreciprocal coupling, with respect to the frequency-dependent device, of the first wavevector compared to the second wavevector.

摘要： A magnet-free non-reciprocal device realized using modulated filters. The device includes one or more filters in one or more branches, where each branch connects two ports or a port and a central node. The poles and zeros of each of the first, second and third filters are modulated in time such that degenerate modes at each pole and zero is split thereby destructively interfering at one or more output ports and adding up at another output port allowing non-reciprocal transmission, isolation and/or non-reciprocal phase shift. The device is able to realize a magnet-free full-duplex communication scheme implementing a magnet-free circulator for radio frequency cancellation or a magnet-free isolator or gyrator.
