Abstract :
Denote the current vector, the voltage vector, and the power dissipated in a resistive reciprocal passive lumped, or distributed, n-port by {i, e, P}, respectively. Consider the two actual, and one hypothetical, regimes {i1, e1, P1}, {i2, e2, P2}, and {i1, e2, P}. It is shown that P ≤ √P1P2.
