Robotic aided dense medium target fabrication

Experimental studies of millimeter-wave scattering in discrete random media and from rough surfaces - Summary

“…However, light materials such as styrofoam have a dielectric constant of only 1.05 at the microwave frequency. Another approach is the fabrication of random media by embedding particles into a thin layer of soft materials [24][25][26][27][28]. To embed particles, holes with a slightly smaller diameter than that of the particle are machined at positions generated by a random number generator.…”
