This forum has already been very helpful in refining my ideas. I have another question about an application involving high power em fields at between 1 to 2.5GHz:
What is the best dielectric to use at these frequencies? I'm thinking about a material to bind copper wire strands together (may even have to be superconductor). Possibly cooling pipes will also be included, but I'm keen that these are seperate from the field wires until I investigate the design further. Ideally the dielectric should have good mechanical properties, as well as no UHF heating (or shielding).
My first thought was epoxy-resin, since this allows me to position the wires first before setting. I'm willing to consider other plastics, but am keen to avoid expensive injection mold tooling. I have used Nylon in the past, since this can be machined. A friend has even suggested glass or carbon reinforced resin, since these are very robust for a given weight.
Does anyone have any ideas/suggestions?
