As shown in figure 1, being a kind of power limiting device based on ELC electric resonance metamaterial structures for providing of the invention, bag
Include at least one metamaterial structure unit, each metamaterial structure unit include substrate, the artificial micro-structure on substrate,
And load on varicap in artificial micro-structure；The artificial micro-structure is ELC electric resonance metamaterial structures, two ends
Metal wire respectively has an opening, and PIN diode (Skyworks SMS 7621-079LF) is loaded at intermetallic metal line opening.
Further, metamaterial structure of the invention can be processed by circuit printing techniques.Fig. 2 is super for the present invention
Voltage at material structure unit intermetallic metal line opening reflects the voltage amplification effect at opening with the change curve of frequency
Should.
The present invention loads PIN diode at intermetallic metal line opening, i.e., introduce non-thread in metamaterial structure unit
Property element, makes metamaterial structure unit have the nonlinear response of electromagnetic wave；Simultaneously as being imitated with voltage amplification at opening
Should, therefore, it is possible to drive diode operation.
The present invention can change the state that is switched off and on of PIN diode by electromagnetic wave power, further optionally
Transmitted electromagnetic wave.Under incoming electromagnetic wave power high, PIN diode conducting, the metamaterial structure unit of script is destroyed, super material
Material structure decays electromagnetic wave in 2GHz to 4GHz.Under low incidence electromagnetic wave power, PIN diode cut-off, metamaterial structure
Electromagnetic wave is allowed to pass through in 2GHz to 4GHz.Fig. 3 is metamaterial structure unit of the present invention in 2 kinds of working conditions of PIN diode
Under stickogram；Fig. 4 is transmission coefficient figure of the metamaterial structure unit of the present invention under 2 kinds of working conditions of PIN diode.
Wherein R=5000 represents PIN diode cut-off, and R=12 represents PIN diode conducting.
