I measured the thinkness of some (Sainsbury's own brand) foil at 0.03mm. This equates to 0.13 skin depths. It is even worse. I read the micrometer wrong, a very ancient one calibrated in those US units of 25.4mm called inches, (cost nothing so I live with it) The kitchen foil is 0.02mm thickness, so 0.09 skin depths Current penetration EXP(-0.09) = 0.91 so only 9 percent screening at 137kHz Andy 'JNT |
