Surface Wave Multipath Signals in Near-Field Microwave Imaging
Figure 9
Surface wave attenuation as a function of frequency for (a) the planar mode at the interface between Plexiglas and the bath for a 15.2 cm length and (b) the coaxial mode with a lossy dielectric (80 : 20 glycerin : water bath) surrounding a metal conductor for 5 and 10 cm lengths.
