  In this work we have done phenomenology based model calculations for some of
the thermodynamic and electrodynamic properties of the strongly correlated
superconductors of Cuprate type. The method involves the application of the
theoretical result for electronic specific heat in the normal phase from
Marginal Fermi Liquid theory to the Gorter-Casimir two fluid model to derive
the temperature dependence of the critical magnetic field corresponding to a
type-I system, using the standard variational technique. We also applied this
modified two fluid scheme to the London theory and obtained an expression for
the temperature dependence of the magnetic field penetration depth in the
superconducting phase. Our results are in fairly good agreement with other
theoretical results based on different approaches, as well as with the
experimental results.
