Abstract: The THz waveguides disclosed herein are used to transmit signals having a THz frequency in the range from 0.1 THz to 10 THz and include an alumina core surrounded by an optional cladding. The core may have a diameter (D1) in the range from 10 μm to 500 μm and may be comprised of a ceramic ribbon having a dielectric constant (Dk). The optional cladding may have a dielectric constant (Dk) less than the core. The THz waveguides can be formed using a continuous firing process and nano-perforation technology that enables access to a wide form factor range. In one example, rectangular waveguides, or ribbons, may be fabricated in the 10 μm to 200 μm thick range at widths in the range from sub-millimeters to several meters and lengths in the range from millimeters to several hundred meters.

Abstract: A method of plugging a filter, comprising: positioning a mask layer over the filter comprising a plurality of intersecting walls, wherein the intersecting walls define at least one channel between the intersecting walls; perforating the mask layer proximate the channel to form a hole, wherein the hole extends around a portion of a perimeter of the channel such that the mask layer defines a flap extending over a center of the channel; passing a plugging mixture into the channel through the hole in the mask layer; and sintering the plugging mixture to form a plug within the channel.

Abstract: A ceramic sheet includes a first surface, a second surface opposite the first surface, and a pair of parallel edges extending therebetween. A thickness of the ceramic sheet is defined between the first and second surfaces, a width of the ceramic sheet is defined between the pair of parallel edges, and a length of the ceramic sheet is defined as a dimension orthogonal to both the thickness and the width. The thickness is less than or equal to 100 μm, the length is greater than or equal to 10 m, and the width is less than or equal to 12 mm. The ceramic sheet has a grain size of less than or equal to 0.2 μm and a porosity of less than or equal to 5%.
