    of microwaves?

    Microwave magnetrons are useful because they produce an EM frequency which water molecules are highly effective at absorbing.
    I can't think of a reason why similar technology couldn't be used to generate infra red frequencies, but there are many ways to generate IR that are probably more efficient.
    A standard electric bar fire element probably is.
