System and a method for reducing particulate pollutants in air, using pulsed electromagnetic waves

A method for reducing a proportion of particulate matter suspended in air, the method performed by a device, and the method comprising:

• generating, by a signal generator, a radiofrequency signal of a predetermined frequency;
• power amplifying, by a power amplifier, the generated radiofrequency signal for feeding to a transmitting antenna for radiating as an electromagnetic wave;
• periodically interrupting, by a pulse width modulator, the power amplified radiofrequency signal from reaching the transmitting antenna, for a predetermined duration, for generating a pulsed radiofrequency signal, wherein the predetermined duration of the periodic interruption is adjusted based on one or more of an ambient temperature and a relative humidity at a geographical location of the device, and wherein
• the radiofrequency signal is pulsed with variations in echo train length, duty cycle, and pulse amplitude according to the ambient temperature and the relative humidity at the geographical location of the device;
• and
• feeding the pulsed radiofrequency signal to the transmitting antenna and radiating pulsed electromagnetic radiation into the air by the transmitting antenna.
