Unit to wavelength ratio

  1. Jan 31, 2014 #1
    hi friends, can any body clear my concept about the following sentence.

    " if we use substrates with higher permittivity, like quartz or GaAs that has been used in previous successful experiments, the unit cell will have smaller unit-to-wavelength ratio".

    You obviously took the quote from somewhere. It is the policy of this subforum that you must cite your sources as one would when writing a scientific paper.

    So please do that. Otherwise, it is difficult to have a clearer picture of the larger context.

    As a guess...

    It's just a roundabout way of saying denser substances have a higher permittivity (generally speaking).

    But yeah, we can't be sure without knowing the context of the statement.
