Reflection & Transmission at Normal Incidence
Inside this lesson
- Apply boundary conditions for tangential E and H fields to derive the reflection and transmission coefficients at normal incidence
- Calculate Γ and τ given the intrinsic impedances of two media
- Predict whether the reflected wave is phase-inverted or in-phase based on the impedance ratio
- Recognize that the same mathematical structure will reappear in transmission-line reflection in the next lesson
