Query: In-situ microwave characterization of ferromagnetic microwires-filled
  polymer composites: a review   This review describes the emerging research area and relevant physics of
polymer-based composites enabled by amorphous ferromagnetic microwires.
Fruitful results ranging from their tunable magnetic field and mechanical
stress properties and influences of direct current on their microwave behavior
are displayed in addition to the brief analysis on the underlying physics. The
multifunctionalities exhibited strongly imply a variety of potential
applications such as structural health monitoring and high-performance sensors.
This article underlines that the future challenge mainly lies in proper
microwire tailoring in expectation of a better microwave performance of
microwire composites
