Is it possible, and if so, how should we modify a typical oven magnetron so as to produce higher frequencies of EM radiation?

I know, but with modifications?davenn said:no, they are designed to oscillate at a specific frequency
change the frequency so as to resonate with the other components of food, besides the water in food.davenn said:and what dangerous things were you planning to do with 100's of Watts of microwave power ?

Wikipedia said:Sometimes, microwave heating is explained as a resonance of water molecules, but this is incorrect; such resonances occur only at above 1 terahertz (THz).
Wikipedia said:The microwave frequencies used in microwave ovens are chosen based on regulatory and cost constraints. The first is that they should be in one of the industrial, scientific, and medical (ISM) frequency bands set aside for non-communication purposes. For household purposes, 2.45 GHz has the advantage over 915 MHz in that 915 MHz is only an ISM band in the ITU Region 2 while 2.45 GHz is available worldwide. Three additional ISM bands exist in the microwave frequencies, but are not used for microwave cooking. Two of them are centered on 5.8 GHz and 24.125 GHz, but are not used for microwave cooking because of the very high cost of power generation at these frequencies. The third, centered on 433.92 MHz, is a narrow band that would require expensive equipment to generate sufficient power without creating interference outside the band, and is only available in some countries.
i need magnetron specifics thoughBaluncore said:

A microwave oven does not operate at a resonant frequency of water. Any frequency will do.tade said:I know, but with modifications?change the frequency so as to resonate with the other components of food, besides the water in food.
A magnetron is a type of vacuum tube used in microwave ovens to generate high-frequency electromagnetic waves. It works by using a strong magnetic field to control the movement of electrons, which then interact with a resonant cavity to produce microwaves.
The highest frequency that can be achieved from an oven magnetron is typically around 2.45 GHz, which is the frequency used in most household microwave ovens. However, some industrial magnetrons can reach frequencies up to 10 GHz.
Technically, it is possible to increase the frequency output of an oven magnetron by modifying its design or using specialized components. However, this is not recommended as it can be dangerous and may damage the magnetron or the microwave oven.
The output frequency of a microwave oven does not directly affect the cooking speed. Instead, it is the power output (measured in watts) that determines how quickly food is cooked. Higher frequencies may allow for more precise cooking, but it will not significantly impact the overall cooking time.
No, there are no known health concerns related to the higher frequencies produced by an oven magnetron. Microwave ovens are designed and tested to ensure they are safe for use in households. However, it is important to always follow proper safety precautions and use microwave-safe containers when heating food in a microwave oven.
