ITMS 2018: Circular Fractal Structure Outperforms Conducting Plate at Dampening GHz Electromagnetic Waves
Peer-reviewed physics research from VGTU, ITMO University, and the Aires Human Genome Research Foundation — demonstrating that the fractal diffraction geometry underlying Aires technology achieves superior electromagnetic perturbation damping in the gigahertz range.
Research Overview
This peer-reviewed paper investigates how a circular periodic fractal structure etched onto a silicon crystal (100 orientation) interacts with electromagnetic radiation in the gigahertz frequency range. The study was presented at the 2018 International Topical Meeting on Litho-Metrology Systems (ITLMS) in Panevėžys, Lithuania, and published in IEEE conference proceedings.
This is the core physics paper validating the fractal diffraction mechanism that underlies Aires technology. The circular periodic structure tested corresponds directly to the geometry of the Aires Microprocessor’s fractal diffraction grating.

What Was Tested
Test Object
Silicon crystal (100 orientation) with a circular periodic structure — a fractal diffraction grating in a concentric ring geometry. This is the same structural principle as the Aires Microprocessor.
Frequency Range
Gigahertz (GHz) frequency electromagnetic radiation — the same range as Wi-Fi (2.4–5 GHz), 4G/LTE (~0.7–2.6 GHz), and 5G (sub-6 GHz and mmWave) signals.
Comparison Condition
A conducting plate of identical physical dimensions to the fractal silicon structure, tested under identical conditions. This is the gold-standard comparison: the best conventional material for electromagnetic shielding.
Measurement Mode
Optical reflection mode measurement of electromagnetic perturbation (EP) damping efficiency.
Key Finding
This is a significant result: conventional wisdom holds that conducting plates are the most effective passive shielding geometry. The fractal silicon structure’s superior performance indicates that the diffraction mechanism — coherent redistribution of electromagnetic energy — is more effective than simple reflection or absorption by a conductor.
Physical Mechanism
The circular fractal geometry creates a self-similar diffraction pattern across multiple spatial scales. When electromagnetic radiation encounters the structure, it undergoes coherent diffraction — the waves are redistributed and transformed rather than simply reflected or absorbed. The constructive and destructive interference patterns generated by the fractal geometry suppress the electromagnetic perturbation more efficiently than the specular reflection from a flat conducting surface.
This mechanism is distinct from conventional shielding, which works by absorption or specular reflection. The fractal diffraction approach does not require high conductivity or thickness — it works through geometry. This is why the comparatively thin silicon structure can outperform a conducting plate of the same dimensions.
Connection to Aires Technology
The Aires Microprocessor is fabricated by applying a circular fractal periodic structure to a silicon wafer substrate using photolithography — the same process used in semiconductor manufacturing. This peer-reviewed study validates the core physical mechanism: the fractal geometry, not just the silicon material, is responsible for the observed electromagnetic interaction, and this geometry achieves measurably higher perturbation damping than a conventional conducting structure of equivalent size.
