Absorption coefficient of aluminium for microwaves

  1. Aug 5, 2013 #1
    I am looking for an exact value of absorption coefficient of aluminium for microwaves, but I can not find it in the internet. Anyone knows where I can find it?

    Are you aware that, since aluminum is highly conductive, it mostly reflects rather than absorbs microwaves?

    apart from what Marcusl said, and I agree with,

    if you need an exact value .... then what is the exact frequency of the microwave radiation
    absorption amount will change with frequency for any substance
