Science

Which risk significantly increases in a coupled LC circuit operating close to the electromagnetic skin depth?

A)Radiative energy dissipates due to impedance mismatch
B)Thermionic emission rises from electrodes
C)Dielectric breakdown weakens insulation strength
D)Eddy current generation raises coil temperature

💡 Explanation

Radiative dissipation increases at the skin depth because energy flow couples to free space through impedance mismatch of the electromagnetic wave. Therefore energy is radiated away as a loss, rather than remaining in intended resonant oscillation because inductive/capacitive effects are shorted out.
