  At terahertz (THz) frequencies there are few experimental works which
demonstrate filter synthesis to obtain a desired filter response (i.e.,
Chebyshev, Butterworth, Bessel, etc.). Currently, the majority of literature
perform THz filter analysis, that is, characterizing the filter response after
design procedure. In this paper, we apply filter synthesis methods from
microwave engineering to design several integrated planar low-pass filters fc =
0.8 THz). We find that the transmission characteristics align with theory and
simulation.
