Hereby wave direction any direction reflects, and realizes the adjustable control to THz wave.
To achieve these goals, the present invention is achieved through the following technical solutions：
The present invention shares 4 basic structural units, and each construction unit is in addition to R parameter, remaining parameter all same.The present invention
4 R parameter values of middle selection are respectively：27um, 30.7um, 38.5um, 51.5um, each parameter value correspond to one it is different
Cellular construction.In order to facilitate description, R parameter value is by we：27um, 30.7um, 38.5um, 51.5um 4 cellular constructions
It is respectively designated as：Unit 1, Unit 2, Unit 3, Unit 4.This 4 units will be shown each under the vertical irradiation of THz wave
From exclusive phase.In certain frequency range, the phase difference between adjacent cells is about 90 degree.We press this 4 units
Certain rule is arranged in two dimensional surface just forms THz wave reflex control device, when THz wave vertical irradiation is controlling
When on device, the arrangement for changing the cellular construction species of composition reflex control device or changing composition reflex control device cellular construction is suitable
Sequence can be so that THz wave reflects to different directions.
The present invention has the advantages that simple in construction, size is small, small volume, is easily integrated, broadband, and control accuracy is high.
