What Causes the Formation of Plasma in a Microwave?

AI Thread Summary
Creating plasma in a microwave involves ionizing the air surrounding a lighted match placed in a cork holder, covered by a glass beaker. The experiment results in a visible blob of plasma at the top of the beaker. While there was a humorous mention of Phosphorus and Potassium Chlorate in the match head, the consensus is that the plasma formation is primarily due to the ionization of air. The discussion highlights the simplicity of the experiment and the basic principles of plasma formation. Overall, the focus remains on the ionization process as the key factor in creating plasma.

Hi everyone,

I am about to enter a local Science Fair and my project revolves around creating plasma in a microwave. This is a great experiment, all you do is stick a lighted match in a cork, (or something to hold the match in place) put it in the microwave with a glass beaker over the match and switch it on. The resulting effect is a large 'blob' of plasma in the top of the beaker. But I was wondering, when this happens is it the air surronding the match being ionised, or is it the Phosphorus and and/or Potassium Chlorate in the match head?

Thanks in advance.

Well, even with my very minimal knowledge about plasma, I know that plasma is formed by ionized gas(air), nowhere in the Wikipedia page did it mention Phosphorus or Potassium Chlorate! That was a joke.. But really, I would say the air is being ionized if you truly have created plasma. My answer is probably not what you were looking for but I thought I'd give my two cents since nobody else has commented at the time I was composing this.

Thanks TheSatirist, you probably gave about 10 cents there, not just 2
 
Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
