Web21. jan 2008 · The reflected RF waves cause these conditions to occur: The reflected RF waves travel farther and arrive later in time than the direct RF wave. The reflected signal loses more RF energy than the direct route signal, because of the longer transmission route. The signal loses energy as a result of the reflection. WebOrdinary reflection (as would occur at a mirror) would lead to a reflected beam having the in-plane wave vector component −k · sin θ. Due to the grating's phase modulation, one can have additional reflected components with in-plane wave vector components −k · sin θ ± 2 π / d. These correspond to the diffraction orders ±1.
