  The paper presents new results in the field of super high-speed and
multi-valued signal processing. Writting digital information into spatial
structures (topological charts) of electromagnetic field pulses allows to use
passive circuits for fulfillment several subpicosecond spatial logical
operations. This is confirmed by analysis of several physical effects in solids
and micron circuits, which influence on time delay of signals. A subpicosecond
circuit for spatially modulated signal switching is considered. An analogy
between electromagnetic mode physics and several aspects of quantum mechanics
is studied. On this base a new digital multi-valued device for spatially
modulated signal processing is suggested and modeled. A conclusion on
possibility to design a new threedimensional architecture of super-density IC
has been made.
