文摘
- •
The complex permittivity and dielectric loss are in inverse proportion to the particle size.
- •
With the reduction of particle size, the peak of reflection loss shifts to lower frequency.
- •
With the reduction of particle size, bandwidth (<−10 dB) becomes broader.
- •
The maximum RL of the smaller nanocapsules can be achieved at thinner absorber layer.
