Optimisation of Mach-effect thruster geometries for maximum coherent force output
Voss, E.; Chen, M.; Mehta, R. · Journal of Advanced Propulsion
Systematic optimisation of Mach-effect thruster geometries using finite-element analysis and torsion-balance validation. 340% improvement in force-to-power ratio relative to the 2023 reference design.
- 2025Materials
Metamaterial shielding for parasitic-radiation suppression in electromagnetic drives
Park, J.; Voss, E. · Physical Review Applied
Metamaterial configurations for radiative containment in electromagnetic propulsion systems. Simulated 92% containment efficiency at the relevant microwave bands; experimental follow-up in progress.
- 2025Mathematics
Numerical relativity simulations of exotic-matter spacetime geometries
Okonkwo, S.; Mehta, R. · Classical and Quantum Gravity
A 4th-order BSSN-NOK pipeline for integrating Einstein field equations under weakened and null-only energy conditions. Applied to a family of Alcubierre-type warp bubbles.
- 2024Propulsion
Thermal drift characterisation of sub-μN torsion balances
Petrova, A.; Park, J. · Review of Scientific Instruments
Thermal-drift modelling and active compensation for cryogenic torsion balances at 10⁻¹² N resolution. Apparatus and calibration protocol made open.
- 2024Physics
Numerical evidence against negative-mass accumulation in inertial-drive configurations
Okonkwo, S.; Mehta, R. · Physical Review D
Lattice-regularised vacuum-polarisation calculations in time-dependent accelerated backgrounds. Negative-mass solutions not supported under reasonable assumptions on the quantum stress-energy tensor.
