This paper reviews microwave on-chip resonators with emphasis on quality-factor (Q-factor), and techniques enhancing Q-factor. The review discusses both planar microstrip and waveguide structures, with the integration of the latter emerging as a subs

Efficient electromagnetic analysis of very large antenna arrays is important for various applications, including e.g., radio astronomy. The method of moments (MoM) is generally the most suitable computational electromagnetics method to deal with such

This paper proposes an efficient, fast-converging iterative scheme based on many local method of moments (MoM) solutions, to accurately solve the surface currents on large, single-element excited antenna arrays. Embedded element pattern computations

A new iterative method is presented, for the efficient method of moments (MoM) analysis of large antenna arrays with identical, disjoint elements. The method is an extension of the domain Green’s function method (DGFM). At each iteration, a local d

An efficient technique for improving the accuracy of the domain Green's function method (DGFM) for the analysis of large finite antenna arrays with strong mutual coupling, is presented. The technique employs rigorous method of moments (MoM) analysis

In this paper, the low-loss coaxial probe fed microwave cavity filter is presented. The filter has recently shown great performance improvement in its selectivity and S-parameter response, but the rate of signal to noise ratio due to spurious modes i

This paper presents the design and optimization of a square spiral using layout optimization technique. The ohmic losses are reduced by varying the width of the spiral segments with the outermost segment having a wider width and the innermost segment
