A simple technique involving transmission through a copper-wire meander line is utilized to probe the microwave absorption of the heavy-fermion superconductor CeCoIn5 in the frequency range below 20 GHz. The measurements do not show features identifiable with absorption into order parameter collective modes, as observed earlier in UBe13, but instead show a rather rapid change in the transmitted signal vs. temperature in the range 8.5-10.0 GHz, possibly implying the opening a low-energy dissipation channel in CeCoIn5.
