Wide-band Rotation Measure Synthesis

Faraday Rotation Measure Synthesis

We extend the rotation measure work of Burn (1966) to the cases of limited sampling of λ2 space and non-constant emission spectra. We introduce the rotation measure transfer function (RMTF), which is an excellent predictor of nπ ambiguity problems with the λ coverage. Rotation measure synthesis can be implemented very efficiently on modern computers. Because the analysis is easily applied to wi...

Asymmetrical-fed RHCP Wide-Band Slot Element for X-Band applications

An outstanding square slot element, for x-band wireless applications with asymmetric coplanar waveguide fed (CPW) is proposed. Various shapes of metallic strips are utilized as grounded stubs for providing Right Hand Circular Polarization (RHCP) functionality and wide-band properties. By adjusting the proposed stubs and hook-shaped radiator, length and positions, wider impedance band width is o...

Wide Band Nonuniform Substrate Integrated Waveguide (NSIW) Wilkinson Power Divider

A new wideband Wilkinson Power Divider which use the nonuniform substrate integrated waveguide (NSIW) method is presented in this paper. This structure utilizes NSIWs instead of the uniform quarter wavelength SIWs in conventional Wilkinson power divider. The proposed structure is analyzed by odd and even mode analysis. The proper NSIW section widths can be extracted by using even mode while the...

Self-Equalized Distributed Amplifier for Wide Band Optical Transceivers

A novel technique for a self-equalized distributed amplifier is presented by showing the analogy between transversal filters and distributed amplifier topologies. The appropriate delay and gain coefficients of amplifier circuit are obtained by a Fourier expansion of the raised cosine spectrum in the frequency range of 0-40GHz.
