A coaxial transmission line carrying an RF signalis perfectly matched to the load. Consider the cross-section of the line, at a plane where the instantaneousvoltageis at its maximum value. How will the curl of the E-field vary over this cross-section?

A

Increases from the center to the outer conductor

B

Decreases from the center to the outer conductor

C

Zero everywhere

D

Constant value proportional to the RF voltage
