VGTU Phase II Report (2017): Array Testing of Aires Resonator-Converter Groups
Institution: VGTU — Laboratory of Photovoltaic Technology, Department of Physics | Customer: UAB AIRESLITA | Year: 2017
Investigators: Dainius Jasaitis (Head of Laboratory), Prof. Artūras Jukna (Head of Physics Dept.)
Context
Direct continuation of the VGTU Phase I study (2016), which found a 27% average reduction in electric field intensity at 0.9–2.5 GHz when individual Aires R-Cs were applied to a transmitter in near-field optical reflection mode. Phase II extended the investigation to 2D arrays of four R-Cs to test group effects and characterize threshold power dependencies.
Methods
Four R-Cs of the same type mounted on a panel transparent to 0–8 GHz radiation. Two configurations: (a) four Aires Black Crystal R-Cs; (b) four Aires Shield R-Cs. Source: 800 W transmitter at 2.5 GHz. Equipment: Signal Hound Spectrum Analyzer with FFT analysis. Measurements taken at 2λ–10λ receiver distance in both optical transmission and optical reflection modes.
Key Findings
Optical reflection mode: Electric field amplitude in the 0.9–2.5 GHz band decreased by an average of 20% due to constructive interference between incident and reflected EM waves. Maximum damping efficiency when R-C group positioned within 3λ of receiver.
Optical transmission mode: Group R-C interaction equivalent to a metal plate screening the incident wave electric component.
Threshold power (Emin): Minimum activation power ≥ 2 W at 0.9–2.5 GHz. At higher frequencies, Emin was found proportional to photon energy (hν) and the square of electric field amplitude (E²). This provides a physically grounded model of the threshold activation mechanism for the first time.
Group optical transmission: Arrays showed optical transmission not exceeding 8%, confirming groups reflect the majority of interacting energy.
Significance
The Emin ∝ ƒ(hν, E²) relationship — established here for the first time — informed the MEMS design work in the C-series R&D reports (C16S, C28S, C32S) and is referenced in the Springer ICICT theoretical modeling papers. The Phase II findings confirmed that the field reduction effect is reproducible across group configurations.
