Yes indeed. Two dircuits in separate shielded enclosures can be coupled
with a coupling capacitor and only the E-field gets through. Similarly,
two transformer windings separated by a Faraday shield are completely
coupled magnetically and have no electrostatic coupling. I`ve worked in
several broadcast stations and all towers were so coupled to avoid
capacitive coupling which could give advantage to harmonic frequencies
over the broadcast fundamental frequency.
