Substrate with sinuous web and particulate filter incorporating the same

A filter comprising a ceramic filter structure comprising:

• a first support web, a second support web, and a sinuous web between the first and second support webs, wherein
• the first and second support webs and the sinuous web extend parallel to a longitudinal axis of the filter structure,
• the sinuous web comprising transverse web portions and bridging web portions, the bridging web portions connecting adjacent transverse web portions in a sinuous shape in a cross section perpendicular to the longitudinal axis,
• the sinuous web being connected to the first and second support webs by respective first support legs and second support legs, the support legs connecting respective bridging web portions and support webs,
• the filter structure defining a plurality of fluid channels extending along the longitudinal axis of the filter structure from a first lateral end to a second lateral end of the filter structure, and
• a plurality of ceramic plugs that block a plurality of fluid channels such that a first set of ceramic plugs block a first set of fluid channels at the first lateral end of the filter structure and a second set of ceramic plugs block a second set of fluid channels at the second lateral end of the filter structure, wherein
• each fluid channel from the second set of fluid channels is adjacent to a fluid channel from the first set of channels,
• each fluid channel comprises a first portion defined between adjacent transverse web portions and a second portion defined between adjacent support legs,
• the first set of ceramic plugs block each first portion of the second set of channels and block each first portion and each second portion of the first set of fluid channels at the first lateral end,
• each second portion of the second set of fluid channels is not plugged at the first lateral end,
• the second set of ceramic plugs block each first portion of the first set of channels and block each first portion and each second portion of the second set of fluid channels at the second lateral end, and
• each second portion of the first set of fluid channels is not plugged at the second lateral end.
