Material with specific elec. conductivity

  1. Nov 19, 2014 #1
    Dear Friends,

    I am working on a project in which we need to shield an electrical field with a heavy 1 MHz component, at the same time, sparing the magnetic field as much as we can. With our limited knowledge, we came to the conclusion that a material with 10 kOhm conductivity would do this all-right. However, we are having a hard time to find such material. So far we tried using plastic painted with graphite. Despite that we could reach 10 kOhm, such graphite paint is very fragile and its performance decay over time..

    So, this brings me here.. Does it exist any stable composite material that can be produced to have electrical conductivity of 10 kOhm? Conductive elastomer? Any suggestions would be greatly appreciated!

    Thank you all very much in advance!
