## Abstract We describe a method to determine a material's complex permittivity and permeability over a range of temperatures. Input impedances are calculated from scattering parameters measured with the sample terminated by two offset shorts. These are manipulated to solve for complex permittivity

## Abstract A lowβprofile equilateralβtriangular dielectric resonator antenna (DRA) of very high permittivity (Ξ΅~r~ = 82) is excited with the use of a rectangular waveguide. It is found that the present configuration has a very wide impedance bandwidth of 11.4%, which is 3.8 times of that of the pr
## Abstract Experimental results of the complex permittivity and permeability of carbonyl iron powders are presented. It is found that the complex permeability of these samples is quite similar due to the high content of iron while the complex permittivity of the samples is significantly different
## Abstract A new measurement technique is presented to determine the complex permittivity of a dielectric material. The dielectric sample is loaded in a shortβcircuited rectangular waveguide. The reflection coefficient of the waveguide is measured by Network analyzer and calculated as a function o
