Here we present dispersion characteristic dependencies of the main mode of open cylindrical hollow-core glass waveguides filled with blood and lymph at three different internal waveguide radii and two waveguide materials when the frequency range is of 0.1 GHz to 100 GHz. The pipe waveguides were made of acrylic - glass with the permittivity 4 and glass - ceramic with the permittivity 6.9 materials. The thickness of glass was always 0.5 mm and internal radii of waveguides were 1.5, 1 and 0.5 mm. We also show here the real part of propagation constant of two empty waveguides with the internal radius equal to 0.5 mm for the four hybrid modes at the frequency range of 0.1 GHz to 300 GHz.
