Adopt z to transmission, yElectromagnetic wave to polarization encourages double-function device, and near field emulation and test result are as shown in Figure 6.Can find out, emulation and test result are coincide good, and certain deviation, deflection angle have all occurred electromagnetic waveDegree is 25.5 °, this and theoretical value θt＝arcsin(ξ/k0)=25.7 ° coincide good.
In order to verify deviation bandwidth effect, double-function device is carried out to far field test, adopt z axle transmission yThe electromagnetic wave of polarization incident encourages, and effect is tested as shown in Fig. 7 (a) in its far field, can find out,Within the scope of 8～12GHz, main beam pointing and theoretical value are coincide good, and at centre frequency 10.5GHzPlace, 0 rank reflection is very little, and test wave beam deviation efficiency has reached 72.2%. Fig. 7 (b) has provided 10.5GHzThe far-field radiation directional diagram of place's emulation and test, can find out, the wave beam deviation of 26.5 ° has occurred electromagnetic wave.When Fig. 7 (c) has provided electromagnetic wave normal incidence, the maximum result contrast of theory, emulation and test, canTo find out, three coincide good, has verified the validity of design. In the time of electromagnetic wave oblique incidence, partially theoreticalKnuckle degree can be according to θt＝arcsin(sinθi+ξ/k0) calculate, theory when Fig. 7 (d) has provided oblique incidence,Maximum beam position when emulation and test, same three coincide good, in test, electromagnetic wave incidentWhen direction is-40 °～10 °, wave beam deviation angle and theoretical value are coincide better, when this is less than emulation-60 °～15 °, this is mainly because the size of plank is limited, in the time that incident angle is excessive, on plankProjected area reduces greatly, causes phase gradient no longer to meet design requirement.
