Google for coaxial feed through capacitors.

Capacitors and resistors don't ring. Adding inductance can introduce
ringing. but enough resistance can make the resonant circuit
critically damped and the voltages and current will decay
monotonically.

So, when you use a coaxial feed through capacitors on your faraday cage,
do you add a resistor right after the capacitor, to reduce/eliminate
ringing? Or are you just trying that all your inputs on the board have
resistors before whatever op amps or other components that they feed
into?
