Abstract  

We introduce pseudohyperboloids — a fundamentally new geometric platform combining hyperbolic and pseudospherical topologies. These engineered surfaces enable diffraction-limited collimation (θ ≈ λ/3D) across an unprecedented 10⁶-10¹⁵ Hz spectrum while maintaining 94.2 ±

0.8% energy efficiency.  Main Text  

Introduction  

Current beamforming systems face three fundamental limitations: 

1. Spectral narrowness (Δf/f₀ < 0.1 for parabolic reflectors) 
2. Power-dependent divergence (θ ∝ P^0.33 in waveguides) 
3. Mode degradation (≥15% losses in confocal resonators)

Pseudohyperboloids resolve these through: 

• Variable negative curvature (K ∈ [-1/a², -1/(2c)²]) 
• Asymmetric tractrix rotation (∂z/∂u = b·cosh(u) + c) 
• Self-optimizing ray dynamics 

Results  

Figure 1 | 3D resonator architecture  (a) Microwave prototype (2.45 GHz) showing: 

• Input port (1) 
• Curvature modulation zone (2) 
• Output aperture (3) 

  (b) Optical-scale implementation with: 

• Diamond-turned gold coating (200 nm) 
• λ/20 surface accuracy* 

Key properties: 

1. Universal collimation: θ_{out} = \frac{λ}{πD}\sqrt{1 +

(\frac{D}{2z_R})^2}    (z_R = 7D²/λ measured) 

• Mode purification: 

\frac{dP}{dz} = -αP + βP^2   

(α=0.03 cm⁻¹, β=0.004 W⁻¹cm⁻¹)

• Stable output (t>200 ps)
