I understand completely where your coming from i did analyze before trying it to see what was flying around in the spectrum but there easnt which is why i was surprised i got something im working on a bismuth and anodized aluminum reflective chamber also and bismuth based antenna capacitors with graphite and mica so ill post the results when i see what that can accomplish thats just like looking at the stars and realizing there ghosts but thats just relativity in action ill study the optical longitudal waves and see what it enlightens me with always willing to accept where im lacking i appreciate you guys any other ideas on achieving this type of imaging also tried out refractive screens and refractive raw calcite just sharing with you guys some ideas incase you might be looking into the same areas for the reflective receiving i have been working with mercury too but the only thing ive noticed is amplified signal levels with my VNA
