  1. A poster (print format) with a peer-reviewed paper was presented on 11 Aug 2008 at SPIE Optics+Photonics'08 - Nature of Light II: Light in Nature on a newly discovered capability for separating waves simultaneously received from multiple sources using the exponential chirp transform. The transform shifts their respective source spectra in proportion to their distances due to a basic dependence of the phase of every wave with its frequency and total path delay. Chirp transforms have been used in radar and imaging for years, but always in chirp-dechirp pairs, so that this remarkable property was never exposed.

    The present result is as yet theoretical, but is backed by computational tests -- see simulation applet. Efforts are under way for physical validation. If validated, the result would

    • obsolete spectrum allocations and auctions, and multiply channel capacities;
    • make communication inherently interference-free and satellites unjammable, by enabling any radio or cell-phone to select a specific station or source regardless of any number of other transmitters on the same frequencies;
    • allow instant passive ranging of satellites, aircraft, cars, rescue beacons, etc., without radar round-trip delays or triangulation; and
    • enable a new generation of continuously tunable wavelength-transformers that could transform, for example, visible LED light into terahertz or X-rays.

  2. A poster along with a peer-reviewed paper was presented on 29 Jul 2008 (pictures: 1 2 3) at the 6th International Energy Conversion Engineering Conference (IECEC) on a fundamental breakthrough in thermodynamic theory that enables direct conversion from hot particles, potentially raising the Carnot limit to virtually unity (thereby effectively doubling our energy resources). The approach involves using electric or magnetic fields in place of mechanical pistons in order to capture the hot particle energies before their dispersion into the bulk medium by relaxation processes at subpicosecond speeds.

    The approach would be applicable as a "front-end convertor" before traditional conversion in nuclear, chemical and even solar power. Another envisaged application is in IC chips for converting the hot carrier energies before they can cause heating and lattice damage.
