• In this paper, a new Surface Wave (SW) diplexer in frequency bands of 11.6 GHz and 19.3 GHz is presented based on the frequency variations of the refractive angle when an SW enters from a Scalar Impedance Sheet (SIS) to a Tensor Impedance Sheet (TIS). In this structure, a SIS has been placed alongside a TIS, and using three launchers, SW is excited and received on them. To achieve an SW diplexer, the structure is designed in a way that the refractive angle changes in the expected range when SW enters from SIS to TIS. Finally, the proposed structure is fabricated and measured by printed circuit technology. The measurement results at 11.6 GHz and 19.3 GHz show that this structure has 3.6dB and 4.1 dB insertion losses and 33.5dB and 37dB isolations in the two bands, respectively. These measurements are in good agreement with mathematical modelling and simulations.
