Path loss at higher distances is much higher for NLOS in the office due to solid walls in the propagation path. In LOS, the results are converging with increasing distance. In our indoor campaign, these large distances can only be found on corridors. At small distances the path loss is about 10 dB less in the aircraft than in the office for all frequencies, which can also be observed in PL0. The delay...
In Piesiewicz et al., (2005), we proposed an efficient method to model reflective properties of smooth building materials at THz frequencies. It is based on Fresnel equations, which are applied to measured material parameters to account for frequency dependence. However, this technique is adequate for smooth materials only as it neglects scattering losses.The method can be extended to rough materials...
Accurate channel modeling for future THz communication systems requires knowledge of the reflection properties of typical building materials. Using Fresnel's equations it is possible to obtain this data from simple measurements of the dielectric properties in case of smooth material surfaces. We extend this method to model rough surfaces in the specular direction and verify our model with direct reflection...
The paper provides details of the measurements of reflection and transmission properties of common building materials in W-band. The measurements are conducted with a vector network analyzer with high gain horn antennas. In particular, bistatic reflection profiles, reflection scattering profiles and transmission scattering profiles are presented. The measurements provide basic information needed for...
