← ScienceWhich 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.
