Abstract

In this letter, a technique is presented to measure the constitutive parameters of magnetoelectric ferrite materials in the presence of high dc voltages. The traditional coaxial line design has been modified in a manner that it allows for the introduction of high dc voltage (≤ 1000 V) and also it minimizes electromagnetic radiation loss via connections to the magnetoelectric sample. The modified coaxial line is verified through the theoretical calculation and experimental measurements for 50 MHz to 3 GHz frequency range.
