Energy of beamed EM field that can heat human tissue

Click For Summary
SUMMARY

The discussion focuses on the quantification of energy from a beamed electromagnetic (EM) field capable of heating human tissue by 1°C within one hour at a distance of 2 meters. The parameters include a narrow beam width of 40-60 cm and considerations of frequency, energy emission, and specific absorption rate (SAR). The conversation also addresses the impact of a wall on energy requirements and seeks information on devices or equipment that can achieve these energy levels, particularly in relevant industries.

PREREQUISITES
  • Understanding of electromagnetic wave properties
  • Knowledge of specific absorption rate (SAR) calculations
  • Familiarity with thermal effects of EM fields on biological tissues
  • Awareness of industrial applications of EM heating technologies
NEXT STEPS
  • Research the specific absorption rate (SAR) in human tissues
  • Investigate the properties of microwave and radiofrequency heating
  • Explore industrial applications of focused EM fields in medical devices
  • Learn about the design and operation of RF heating equipment
USEFUL FOR

This discussion is beneficial for researchers in biomedical engineering, professionals in medical device manufacturing, and anyone involved in the application of electromagnetic fields for therapeutic purposes.

I only have a background in mathematics, and I lack knowledge on this matter.

I want to get quantitive value about that problem.

What would be the kind of wave or EM field that could heat human tissu of 1°C in (say a body part like the thigh), say in one hour, at a distance of 2m ?

We could assume that it is some kind of beamed field very narrow, say 40/60cm wide.

What frequencies ? What energy at emission and at reception are we talking about ? What about the cumulative energy (SAR ?) received ?

Assume now there is a wall in front the emission but a small wall. How much must be now the source emission to produce the same effect ?

And final question is what kind of device or industrial/professional equipment could provide that level of energy ? In what industries do you find that ?
