Abstract: Disclosed are embodiments of microstrip and substrate integrated waveguide circulators/isolators which can be integrated with a substrate. This composite structure can serve as a platform for other components, allowing for improved miniaturization of components. Embodiments of the disclosure can be particular advantageous in the high frequency ranges, such as above 1.8 GHz or above 3 GHz, which allows devices to be used in the 5G space.

Abstract: The disclosed technology generally relates dielectric materials and methods of forming the same, and more particularly to a combination of co-fireable dielectric materials that can be attached to each other without the use of adhesives. In an aspect, a composite article comprises a magnetic portion comprising a nickel zinc ferrite. The composite article additionally comprises a non-magnetic portion contacting the magnetic portion, the non-magnetic portion comprising a spinel-structured oxide comprising Mg2-xAl2xTi1-xO4 and having a dielectric constant between about 7 and 14, wherein 0<x?1.

Abstract: Frozen confection composition comprising from 0 wt % to 5 wt % fat, from 0 wt % to 10 wt % protein, a fat to protein ratio of less than 1:1 and an emulsifier; wherein the fat droplets of the homogenised pre-mix of the frozen confection have an average droplet size d (3,2) of below 0.6 micron, and significantly reduced shrinkage of the product is observed on heat shock testing of the frozen confection product.
