Paper Abstract

Since first reported in 1955 the Fermi-Pasta-Ulam (FPU) recurrence phenomenon has been thoroughly studied. Being reproduced in nonlinear electric lines this intermittent physical process became a possible instrument for a structural analysis. The FPU electromagnetic spectrum generated in coupled nonlinear lines proved to cover a wide band of frequencies (10 Hz-10GHz). Generator and a receiver of this spectrum have been developed and tested in different structures including water, electrolytes, blood and biological tissues. The sample under examination was placed between the generator and receiver resonators of the FPU spectrum. Such a system was able to distinguish normal and tumor tissues, healthy and leukemia blood, different water samples. Future research is aimed at the computerization of the system.
