Using this flat transmission line impedance calculator an 18 inch wide
strip of Sheldahl "Novaclad" with 90 mill thick polyimide
K = 3.4 dielectric (3.37 effective) has an impedance of 1.0 ohms.
Meaning the "light bulb" hot resistance will also have to be 1.0 ohms.
giving a capacitance of 5.96e-9 farad/meter And a pulse propagation
velocity of 1.676e8 meters/second (0.558 c ). The ~ 6.0 nanosecond/meter
pulse velocity will limit the PRF to about 1.0e8/sec (100 MHz) and the peak
pulse voltage to about 30 Kilovolts.
Meaning that a roll of one side copper-coated material can be used for
wallpaper on the inside surface of the metal shell of your craft.
Narrower strips decorated with strange symbols can be used as borders,
which might explain the strange "hieroglyphics" of the Roswell wreckage.
"Sheldahl Novaclad products use a proprietary deposition process to join polyimide film and copper. "
