Profile
Alfonso Rueda
Electrical engineering professor emeritus listed in CSULB’s 2012–2013 catalog; stochastic-electrodynamics researcher
Rueda develops mathematical models relating electromagnetic vacuum fluctuations to inertia and gravity. With Bernhard Haisch, he analyzes the radiation momentum flux incident on an accelerating object and derives a relativistic reaction force interpreted as a contribution to inertial mass. The model connects that contribution to how matter interacts with the radiation field; later collaborative work explores accelerated frames and curved spacetime within the same research programme.

Inertia as a zero-point-field Lorentz force
- Bernhard Haisch(Author)
- Alfonso Rueda(Author)
- H. E. Puthoff(Author)
Haisch, Rueda and Puthoff propose that inertia, the resistance of matter to acceleration, arises from interactions with electromagnetic vacuum fluctuations. Their 1994 model represents matter through hypothetical charged constituents that oscillate like tiny springs. They calculate the magnetic part of the Lorentz force on these constituents during constant proper acceleration (measured in the particle’s momentary rest frame), averaging over the fluctuating field. The resulting force is proportional to acceleration, with its proportionality coefficient interpreted as inertial mass. Its magnitude depends on an unspecified internal mass and a high-frequency interaction limit set by the constituents’ assumed Planck-scale size. This limit restricts the response of matter, not the vacuum spectrum itself. In the final force expression, the authors select the sign that opposes acceleration, consistent with the resistance they seek to explain.

Contribution to Inertial Mass by Reaction of the Vacuum to Accelerated Motion
- Alfonso Rueda(Author)
- Bernhard Haisch(Author)
Rueda and Haisch develop a stochastic-electrodynamics model of inertia by transforming electromagnetic zero-point fields for an object undergoing constant proper acceleration. They interpret absorption or scattering of the resulting momentum flux as a reaction opposing acceleration, with an effective mass depending on the object’s volume and frequency-dependent coupling. That coupling must decrease at high frequencies, and the momentum integrals require a specified integration convention. A covariant appendix includes electromagnetic stresses, removes the earlier 4/3 factor and recovers the standard relativistic four-momentum form. The calculation addresses the electromagnetic contribution, leaves microscopic interaction dynamics unspecified and treats extension to general motion as an argument requiring further explicit examples, rather than a completed account of all matter’s inertia.

Inertia as reaction of the vacuum to accelerated motion
- Alfonso Rueda(Author)
- Bernhard Haisch(Author)
Rueda and Haisch propose that part of inertia, the resistance to acceleration, could arise from interaction with the electromagnetic vacuum. Their calculation describes an accelerating object encountering a flow of momentum in zero-point radiation, the background fields used in their model. They interpret absorption or scattering of that radiation as a force opposing acceleration. The proposed mass contribution depends on the object’s volume and the fraction of radiation interacting with it at each frequency. That fraction is assumed to decrease at high frequencies, limiting the contribution of those frequencies. The calculation covers forces along the direction of motion. The microscopic interaction remains unspecified, and the authors leave a quantum derivation and the connection to general relativity for further work.
