Accompanying drawing explanation
Fig. 1 is the structural representation of Meta Materials wave-absorber resonator.
Fig. 2 is the structural representation of the Meta Materials wave-absorber being integrated with solaode.
Detailed description of the invention
Below in conjunction with the accompanying drawings of the present utility model being embodied as is described in detail.
Operation principle of the present utility model be sunlight on semiconductor crystal, semiconductor crystalline material absorb photon
After, produce electron-hole pair；Then, the most contrary photo-generated carrier is by electrostatic field produced by PN junction in quasiconductor separately；
Finally, photo-generated carrier is by collected by the two poles of the earth of solaode, namely by resonator and the earth plate of Meta Materials wave-absorber
Collect, and produce electric current in circuit, thus obtain electric energy.
The structure of Meta Materials wave-absorber resonator is as it is shown in figure 1, a=9mm, a length of wide 1.618 times, i.e. and b=9 ×
1.618mm, c=7mm, the thickness of resonator is 0.035mm, indirect resistance in gap.
In Fig. 2, the superiors of Meta Materials wave-absorber are the resonator 1 being made of copper, the electricity connected in the middle of resonator gap
Resistance 2, the dielectric-slab 3 of resonator lower floor is made up of semiconductor crystal, and as the dielectric-slab of Meta Materials wave-absorber, last layer is for connecing
Floor 4, for the copper of thickness 0.035mm, as the earth plate of Meta Materials wave-absorber.
As Meta Materials wave-absorber and the integrated morphology of solaode, the resonator of Meta Materials wave-absorber is simultaneously as too
The upper electrode of sun energy battery；Semiconductor crystal is as the dielectric-slab also serving as Meta Materials wave-absorber while solar panel；
The earth plate of Meta Materials wave-absorber also serves as the bottom electrode of solaode simultaneously.
Absorbance A (w) can calculate according to A (w)=1-R (w)-T (w).In order to make the absorption of Meta Materials wave-absorber
Rate reaches maximum, and reflectance R (w)=| S11|2With transmission T (w)=| S21|2All should minimize in resonant frequency.S11For instead
Penetrate coefficient, S21For transmission coefficient.Because the backboard of Meta Materials uses metal material, in the range of institute's measured frequency, becoming in metal
The skin degree of depth is less than base metal layer thickness, so absorbance T (w)=0, absorbance is just reduced to: A (w)=1-R (w), by surveying
Amount S11Absorbance A (w) can be measured.
By the analysis of electric field being explained its operation principle: at disresonance frequence point, except the near gaps of resonator,
The electric field in other place is all equally distributed.At resonant frequency point, the upper and lower and resonator gap of resonator has stronger
Electric Field Distribution.Either at resonance point or disresonance point, electric field all concentrates near gaps.At resonant frequency point, absorb
Rate is bigger than disresonance point, and either at the top of resonator, bottom or gap location, Electric Field Distribution is the strongest, and resonance is described
Device absorbs the electromagnetic energy from incidence wave at resonance point.Resonator collects electromagnetic energy by creating electric field at gap location
Amount.
Electromagnetic energy can be converted into exchange by Meta Materials wave-absorber, and therefore, absorption aspect based on energy, Meta Materials is inhaled
Ripple body can use the aspects such as energy absorber system, wireless device, space solar system and sensor application.
For ease of implementing, now provide a concrete simulation example of the present utility model: with the integrated knot of Meta Materials wave-absorber
Structure: thickness is the resonator of the copper composition of 0.017mm, also serves as the electrode of solaode simultaneously；Constitute solaode
The semiconductor crystalline material that 0.4mm is thick, simultaneously as the medium substrate of paster antenna；The metal material of copper conduct that 0.035mm is thick
The bottom electrode of solaode is also served as while antenna ground plate.Simulation result: S11 is 0.1 when 6.689GHz, shows to inhale
Yield can reach 99%.And the thickness of the size or change dielectric-slab by changing resistance can change Meta Materials and inhale ripple
The absorbance of body, makes Meta Materials wave-absorber can have wider application.
This utility model is integrated with Meta Materials wave-absorber by solaode, solves Meta Materials wave-absorber needs
Individually the problem of power supply, so improve resource utilization, improves the sustainability of Meta Materials wave-absorber, it is achieved that equipment
Miniaturization, energy-saving.
The foregoing is only preferred embodiments of the present utility model, within spirit of the present utility model and principle, done
Any modification, equivalent substitution and improvement, all should be within protection domain of the present utility model.
