a decreasing trendno p-value reported

Figure 8 a shows the exact impedance matching values of the CIP@MnO 2 composites, and it can be seen from the figure that the samples with different filling ratios showed a decreasing trend with increasing frequency, and the impedance matching values varied between 0.3 and 0.75, showing stronger impedance matching in the C-band.

an increasing trendno p-value reported

From the images, we can see that the ε ′ values of CIP@MnO 2 composite absorbing materials showed similar trends at different filling ratios, with an increasing trend in the tested frequency band of 2–18 GHz, and the ε ′ values increased as the filling ratio increased.
