[Method for summing up the radio-frequency electromagnetic fields emitted by several sources]

Area of Science:

• Occupational Health and Safety
• Electromagnetics
• Measurement Science

Context:

• Existing methods for assessing radio-frequency electromagnetic fields (EMF) are inadequate for environments with multiple emitters due to frequency-specific hygienic norms.
• Non-selective EMF measurements fail to resolve individual source contributions, hindering accurate hygienic assessment in complex settings like workplaces and settlements.

Purpose:

• To develop a mathematical method for accurately measuring and assessing electromagnetic fields (EMF) in environments with multiple, diverse frequency sources.
• To overcome the limitations of current methods that cannot sum or resolve EMF intensities from separate generators.

Summary:

• A novel mathematical method, building upon approximations of electromagnetic waves as flat waves, is proposed to solve systems of equations derived from EMF measurements.
• The method utilizes polynomial approximation of field intensities and an original algorithm to determine individual EMF contributions from multiple sources.
• This addresses the inability to perform hygienic assessments when dealing with combined EMF from various radio, television, and other emitters.

Impact:

• Enables accurate hygienic assessment of electromagnetic field (EMF) exposure in complex environments with multiple sources.
• Provides a solution for previously unresolvable challenges in measuring and assessing combined EMF in workplaces and settlements.
• Improves the scientific basis for setting and enforcing safety standards related to electromagnetic field exposure.
