FIG. 1.

(Color online) The real, ɛ′, and imaginary parts, ɛ″, of the effective complex permittivity for different values of strain. Measurements were done over the frequency range of 300 MHz-6 GHz. The inset shows a typical tensile stress-strain curve of microwire measured by the Instron 1466 testing machine.

FIG. 2.

(Color online) The real, ɛ′, and imaginary parts, ɛ″ of the effective complex permittivity, measured at 4.1 and 4.7 GHz, as a function of strain λ. The inset shows the strain dependence of the loss factor for these two frequencies.

FIG. 3.

(Color online) (a) The loss factor and (b) microwave absorption spectra for different values of strain.

Images of the wire composite sample under uniaxial elongation corresponding to (a) λ = 1.4%, i.e., elongated but not fractured wires, (b) λ = 2.8%, i.e., showing broken wires.
