Free space measurement of complex permittivity and complex permeability of ferrites materials using transmission reflection method at microwave frequencies / Hasbullah Hassan

Measurement of complex permittivity (ε*) and complex permeability (µ*) at frequency range 7.5 to 12.5 GHz using transmission reflection method are presented for ferrites material. In this method, the complex permittivity and complex permeability will be calculated from the measured value of reflecti...
