Purely geometric.
No sensors. No code.
Three passive phases execute a full radar deception cycle in nanoseconds — with no electronics, no thermal signature, and no emissions to reveal the platform.
Interception
Hostile X-band (10 GHz) radar sweeps the airspace. Waves pass through the RF-transparent fiberglass radome and strike the sphere's outer boundary — an impedance-matched skin (n ≈ 1.0) that eliminates surface reflection.
Sub-λ Refraction
A continuous permittivity profile ε_r(r) = 2.0 − (r/R)², realized via a variable-density Gyroid/BCC lattice, bends every incoming ray to a single focal point on the opposite wall. Bouguer's rule, executed in structure.
Retroreflection
A conductive Cu/Ag hemispherical backing reverses phase by 180° and returns a coherent, co-polarized beam along the exact incoming vector. The enemy screen paints a 1.5 m² flagship-class target.
A continuous math profile, made printable.
Effective medium theory converts a smooth refractive gradient into a variable-density lattice that any commodity SLA printer can reproduce with 50-micron resolution.
Continuous relative permittivity from center to boundary. Guided by Bouguer's rule and Fermat's principle of least time.
1,121 g solid → 350–500 g printed.
Sub-wavelength Gyroid + BCC truss micro-geometry approximates a perfectly smooth refractive gradient via effective medium theory — with 60% less mass and zero impact on tactical UAV range.
Proprietary Slicing
Variable-infill algorithm generates sub-wavelength (λ/10) Gyroid + BCC micro-geometry per shell layer.
Critical Mass Optimization
1,121 g solid → 350–500 g printed. No impact on tactical UAV range or dynamics.
Immunity to ECM
Zero thermal footprint, zero emissions, zero on-board electronics. Invisible to ARMs and hostile jammers.
