(a) Schematic geometry of a horn and waveguide built into the PC. (b) Photograph of a PC horn.
Frequency response for a horn that has alternate layers of rods removed and a horn that has all the layers of rods removed.
Transmission spectra for horns spanning 2, 4, 6, and 8 crystal layers, respectively. The opening angle for all horns is .
