← ScienceWhich risk increases when a microwave waveguide bends sharply?
A)Mode conversion and power loss✓
B)Increased dielectric breakdown strength
C)Enhanced impedance matching occurs
D)Decreased reflection coefficient results
💡 Explanation
Mode conversion causes power loss because a sharp bend disrupts the intended electromagnetic field pattern due to the principle of wave propagation; therefore less energy propagates, rather than enhancing transmission characteristics.
