Coupling and Leakage in RF Systems | Real-Life RF Signals
RF signals readily travel through unintended conduction paths created by capacitive coupling, radiated coupling, and inductive coupling. The movement of RF signals through unintended conduction paths is referred to as leakage. RF systems can be divided into three general categories: full duplex (simultaneous two-way communication)

Difference between capacitive and inductive coupling
The current into a capacitor is proportional to the rate of change of the voltage and so leads the voltage in phase when you apply AC. Capacitive coupling occurs because any two conductors form a capacitor, just not a very good one. You can shield against capacitive coupling by putting a grounded shield around one or both wires.
