  In recent years, interesting materials have emerged which are only available
as micron-scale flakes, and whose novel physics might be better understood
through broadband microwave spectroscopy; examples include twisted bilayer
graphene [1], 2D materials in which many-body phases are observed [2], and
artificial lattices for analog quantum simulations [3]. Most previous
techniques are unfortunately not sensitive for flakes below mm lateral sizes.
We propose a simple technique which does not require sophisticated sample
preparation nor Ohmic contact and show through theory and simulations that one
will be able to qualitatively measure spectral features of interest, and
quantitatively measure the frequency-dependent complex conductivity.
