Bone identification using RF signals


Sorry to disturb. I am quite new to this software and would like some guidance. I have gone through some of the tutorials but havent managed to determine how to proceed.

My goal is to identify distance of the bone from an antenna. Ideally, what I am trying to achieve is to see what quantity of an RF signal compared to the incident signal would be reflected off the bone and whether it is feasible to do it?
I have written simple MATLAB scripts using Gabriel's model for tissue dielectrics but thought could simulate it on sim4life for visual representation.
Would you know how to proceed with this? What do I use, what sensors etc?
