Unconventional superconductivity is a hallmark of exotic quantum matter, with a growing diversity of newly discovered classes, and determination of pairing mechanism is a vital step to understand underlying physics. Van der Waals kagome superconductors are a prominent example that hosts emergent phenomena arising from strong electronic correlations and nontrivial band topology, yet its microscopic origin remains elusive. Detecting electrodynamic response in thin vdW flakes is, however, nontrivial due to their small sample volume and delicate nature, limiting application to conventional bulk-sensitive methods. Superconducting microwave resonators are highly sensitive and coherent, providing a high-resolution platform for probing electrodynamic response of such systems. Here, we integrate hybrid superconducting microwave circuits with vdW flakes, enabling non-invasive measurements of electrodynamic response via contactless coupling that preserves structural integrity. We mitigate parasitic two-level systems that often cause dissipation in microwave systems, enabling suppression of their contribution via geometric optimization and isolation of the intrinsic material response. Remarkably, the temperature dependent superfluid density reveals a T-linear behavior at the low temperatures, indicative of clear observation of a nodal gap structure. This approach demonstrates a pathway for investigating complex correlated materials and for advancing vdW-based quantum device technologies.
