Figure 4

Measured (a) efficiency of probe transmission signal and (b) efficiency of reflected band gap signal (Er) versus Δ2, with Δ3 = 230 MHz when different beams are blocked. First, when Δ1 = 235 MHz, (a1) (b1) no beam blocked, (a2) (b2) E2 blocked, RL represents reference level; Next, when Δ1 = 280 MHz, (a3) (b3) E3 blocked, (a4) (b4) blocked, (a5) (b5) E1 blocked, (a6) (b6) E2 blocked and (a7) (b7) no beam blocked. Total scanning frequency range of Δ2 in each sub-curve is about 240 MHz.
