The ultrawideband (UWB) performance and impulse response parameters of tapered slot antennas with different flare's opening rates and taper types fit to a stepped quarter-wave Chebyshev transformer are presented. This transformer is used to maximize

A new method for the flare's opening rate for a single radiator tapered slot antenna (TSA) is presented. A stepped quarter-wave Chebyshev transformer is calculated to minimize the frequency domain reflection and maximize the power transfer gain. Then

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 introdu

We report the deposition of M-type films by the alternating target laser ablation deposition using Fe2O3 and BaFe4O7 targets to simulate the unit cell of BaFe12O19 rather than a previous used tridymite structure, such as BaFe2O4 for R-block. In fact,

Experiments have been performed to measure magnetoelectric properties of room temperature spirally ordered Sr3Co2Fe24O41 hexaferrite slabs. The measured properties include the magnetic permeability, the magnetization and the strain all as a function

Tapered slot antenna tapers were designed using Chebyshev transformer to minimize reflection and maximize power transfer of the antenna. Cubic spline and exponential curves were fit to the designed steps to smooth the steps. Impulse response for the

In this paper, magnetoelectric effects of Sr Z-type hexaferrite, Sr3Fe24Co2O41, at room temperature is measured. The change in remanence magnetization was measured by applying a DC voltage or electric field across a slab of hexaferrite. Changes of ~

The measured impulse responses of Vivaldi tapered slot antennas employing conventional exponential and cubic-spline taper profiles are presented and compared. The method used to design the tapers is based on a Chebyshev impedance transformer given in
