Energy of beamed EM field that can heat human tissue

In summary, the speaker is seeking information on a specific type of wave or electromagnetic field that could heat human tissue by 1°C in one hour, at a distance of 2m. They are also curious about the frequency, energy, and cumulative energy received, as well as the potential for a smaller source emission to have the same effect. Finally, they are asking about specific devices or equipment commonly found in industries that can produce this level of energy.

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 ?

Related to Energy of beamed EM field that can heat human tissue

1. What is an "energy of beamed EM field"?

An energy of beamed EM field refers to the amount of electromagnetic energy that is being transmitted or emitted through a specific area or beam. This energy can come from various sources such as radio waves, microwaves, and infrared radiation.

2. How does an EM field heat human tissue?

When an EM field is directed towards human tissue, the energy from the field is absorbed by the tissue. This absorption causes the molecules in the tissue to vibrate, which generates heat. The amount of heat produced depends on the strength of the EM field and the type of tissue it is interacting with.

3. Is exposure to an EM field harmful to humans?

It depends on the strength and duration of the exposure. In general, low levels of EM fields are not harmful to humans. However, exposure to high levels of EM fields for a prolonged period of time can cause tissue damage and potential health risks.

4. What are some common sources of beamed EM fields that can heat human tissue?

Some common sources include microwave ovens, cell phones, and medical equipment such as MRI machines. These devices emit EM fields that are specifically designed to heat or interact with human tissue.

5. How can we protect ourselves from potential harm from EM fields?

To protect ourselves from potential harm from EM fields, it is important to limit our exposure to high levels of EM fields. This can be achieved by keeping a safe distance from sources of EM fields, limiting the use of devices that emit EM fields, and using protective equipment when working with high levels of EM fields.
