How does higher substrate permittivity reduce the unit-to-wavelength ratio?

[Noudi]

hi friends, can anybody 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.
