| Abstract: | The excitation and propagation of guided submillimeter waves (λ = 0.337 mm) is demonstrated on stretched, self-supporting sheets of polyethylene (PET) and polyterephthalate (PTER). Prism-film couplers serve for input and output. The PTER films show negative birefringence (n0 = 1.76, ne = 1.68). An attenuation of 0.25 dB/cm was measured for the TM0 mode on a 12 μm thick PTER film. |
