Synthesis, characterization, and microwave properties of polypyrrole/molybdenum trioxide composites
Polypyrrole/molybdenum trioxide (MoO3) composites have been prepared by the in situ polymerization technique. The prepared composites were characterized by Fourier transform infrared spectroscopy and surface morphology by employing scanning electron ...

L‐band depolarised radar back scattering from Martian topographic surface: A numerical study
The interaction of radar signals with a planetary surface is critical for the utility of radar data. Herein, a power‐law roughness spectrum is used to model the roughness and an inhomogeneous vertical permittivity to describe the dielectrics from the ...
