Query: Simulating Quantum Spin Hall Effect in Topological Lieb Lattice of
  Linear Circuit   Inspired by the topological insulator circuit proposed and experimentally
verified by Jia., et al. \cite{1}, we theoretically realized the topological
Lieb lattice, a line centered square lattice with rich topological properties,
in a radio-frequency circuit. We open the topological nontrivial band-gap
through specific capacitor-inductor network, which resembles adding intrinsic
spin orbit coupling term into the tight binding model. Finally, we discuss the
extension of the $\phi=\pi/2$ phase change of hopping between sites to
arbitrary value, and investigate the topological phase transition of the band
structure vary with capacitance, thereby paving the way for designing tunable
lattices using the presented framework.
