    "patent_abstract": "The dynamic ultra-selective waveguide filter (DUST) assembly includes a stack of a plurality of substrate integrated waveguide (SIW) filters, each of which includes a first and second conductive layers, a dielectric layer disposed between the first and second conductive layers to form a waveguide between an input port and an output port, and a plurality of conductive couplers that interconnect the first conductive layer and the second conductive layer through the dielectric layer. The DUST assembly further includes a switch network coupled to the stack of the SIW filters to provide discretely switched tuning or continuous tuning. The switch network includes Super Lattice Castellated Field Effect Transistor (SLCFET) switches to operate the discretely switched tuning or the continuous tuning.",
