Energy of beamed EM field that can heat human tissue

AI Thread Summary
The discussion centers on determining the specific electromagnetic (EM) field parameters required to heat human tissue by 1°C at a distance of 2 meters, focusing on a narrow beam approximately 40-60 cm wide. Key inquiries include the necessary frequencies, energy levels at both emission and reception, and the cumulative energy absorbed, measured in Specific Absorption Rate (SAR). The impact of a small wall in front of the emission source on the required energy output is also examined. Additionally, participants seek information on devices or industrial equipment capable of delivering this energy level and the relevant industries that utilize such technology. The thread concludes with a request for quantitative data to better understand the heating effects of beamed EM fields on human tissue.

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 ?

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'
Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
