● Experimentally confirmed ● Theoretically established ● Speculative but mathematically consistent
Endnotes
- ● Maxwell's equations: experimentally confirmed to extraordinary precision across the full spectrum. See Jackson, Classical Electrodynamics; Saleh & Teich [1, 2].
- ● EM unification of communication and directed energy as same-spectrum engineering: follows directly from linearity of Maxwell's equations. Intensity scaling does not change the field equations. See Nielsen [5]; Benford et al. [9].
- ● Near-field ULF propagation through conductive media: experimentally demonstrated in submarine communications (ELF/VLF) and geophysical survey. See Ellingson [17].
- ● GaN HEMT power density: >40 W/mm demonstrated at X-band. GaN-on-SiC is the standard for military AESA radars. See Pozar [10]; Stutzman & Thiele [11].
- ● Electronic beam steering in phased arrays: deployed in AN/APG-77 (F-22), AN/APG-81 (F-35), and commercial 5G mmWave systems. See Stutzman & Thiele [11]; Rappaport [12].
- ● THz gap and source technologies: QCLs demonstrated at 1–5 THz; photoconductive antennas span 0.1–10 THz. See Saleh & Teich [2].
- ● Quantum cascade laser: first demonstrated by Faist et al. (1994). Emission wavelength determined by quantum well thickness, not bandgap. See Saleh & Teich [2]; Webb & Jones [3, 4].
- ● Modular laser platform with swappable gain modules: architecturally straightforward; shared-resonator designs demonstrated in laboratory settings. System-level product integration is the engineering contribution.
- ● Ti:Sapphire Kerr-lens mode-locking: sub-10 fs pulses demonstrated. Broadest gain bandwidth of any solid-state medium. See Webb & Jones [3, 4]; Saleh & Teich [2].
- ● Nd:YAG harmonic generation: 1064/532/355/266 nm via KTP, LBO, BBO crystals. Standard industrial laser architecture. See Webb & Jones [3, 4].
- ● Excimer laser bond-breaking: 5.0 eV/photon at 248 nm exceeds C-C bond energy (3.6 eV). Clean ablation with minimal heat-affected zone. See Webb & Jones [3, 4].
- ● Compact inverse Compton X-ray sources: demonstrated at MIT (Compact X-ray Source), ASU, and several national labs. Not yet at industrial scale. See Appleby et al. [23].
- ● ICS upshift factor 4γ²: exact relativistic kinematics. For γ = 100, 1064 nm → ~0.1 nm. See Appleby et al. [23].
- ● Laser-wakefield acceleration to GeV over centimetres: demonstrated at LBNL (2006, 1 GeV in 3.3 cm). Coupling LWFA to ICS for compact X-ray generation is an active research frontier.
- ● OAM multiplexing: demonstrated experimentally in both fibre and free-space. Mode orthogonality confirmed. See Saleh & Teich [2].
- ● Optical solitons in anomalous-dispersion fibre: first observed by Mollenauer et al. (1980). Kerr SPM balances GVD exactly. See Saleh & Teich [2].
- ● Control bandwidth hierarchy across EM bands: follows from the timescale separation between ULF (seconds), RF (microseconds), optical (femtoseconds), and X-ray (attoseconds) dynamics. See Franklin et al. [21]; Åström & Murray [22].
- ● VOZDUKH-1 and analog ballistic computation: deployed Soviet system. Mechanical analog computers solving PDEs in real time predate digital alternatives. See historical references in Bluhm [18].
- ● Rydberg polariton blockade: single-photon-level interactions demonstrated. Scaling to macroscopic force generation is a fundamental open problem.
- ● Optical Kerr beam deflection: several-degree deflection demonstrated with high-intensity beams. Practical defensive application requires sustained high-power operation and real-time wavefront sensing. See Saleh & Teich [2].
- ● Schwinger limit: Ecr ≈ 1.32 × 1018 V/m. Predicted by QED; not yet experimentally reached. Current highest-intensity lasers (ELI, NIF) approach 1014 V/m — four orders of magnitude below threshold.
