A method for sending a data from an electromagnetic radiator by polarization modulation of an electromagnetic wave includes radiating from the radiator first and second electromagnetic waves including first and second polarizations respectively, the first polarization being different than the second polarization. The first and second electromagnetic waves form a third electromagnetic wave having a third polarization different from the first or second polarization. The method includes modulating the third polarization responsive to the data by modulating one or more parts of the third electromagnetic wave. The data is sent in the third polarization. A system for sending a data includes an oscillator adapted to generate an oscillating signal, and a phase shifter coupled to the oscillator and adapted to generate a first phase-shifted oscillating signal having a first phase. The phase shifter is adapted to vary the phase difference across a predefined range in response to the data.

Dynamic polarization modulation and control

A self-healing monolithic integrated includes an electronic circuit having a plurality of transistors. At least one sensor is disposed within and electrically coupled to the electronic circuit and configured to sense a performance metric of the electronic circuit. A plurality of actuators is disposed within the circuit. Each actuator of the plurality of actuators has electrically coupled to it a control terminal. The plurality of actuators is configured to perform a selected one of, electrically coupling at least one transistor of the plurality of transistors into the electronic circuit and electrically de-coupling at least one transistor of the plurality of transistors, in response to operation of one of the control terminals to improve the performance metric.
