The phases of adjacent frequencies in a wavepacket evolve along its electromagnetic path at rates proportional to their wavelengths, so that the spectral phase gradient is proportional to the distance /spl tau/ from the source. Scanning of this phase gradient at a controlled rate /spl beta/ at a receiver converts it to a frequency shift /spl delta//spl(More)
Shown is that contrary to common intuition, even an arbitrarily weak attenuating mechanism is sufficient to make the background sky quite dark independently of the size of the universe and the Hubble expansion. Further shown is that such an attenuation already exists in the wave nature of light due to entrapment and diffusion from successive diffractions.(More)
Following host software evolution and experience, it is pointed out that the namespace is the only appropriate application-system boundary even for networking, and that in analogy to host operating systems, the namespace is in fact necessary and sufficient for automatic, efficient management of the Internet addresses and routes. A simple, elegant namespace(More)
Any frequency selective device with an ongoing drift will cause observed spectra to be variously and simultaneously scaled in proportion to their source distances. The reason is that detectors after the drifting selection will integrate instantaneous electric or magnetic field values from successive sinusoids, and these sinusoids would differ in both(More)
A fundamental Doppler-like but asymmetric wave effect that shifts received signals in frequency in proportion to their respective source distances, was recently described as means for a whole new generation of communication technology using angle and distance, potentially replacing TDM, FDM or CDMA, for multiplexing. It is equivalent to wave packet(More)
