PhD Thesis:

Electromagnetic Modeling of Large and Complex Planar Array Structures using Scale Changing Technique (SCT).

Abstract: Large sized planar structures are increasingly being employed in satellite and radar applications. Two major kinds of such structures i.e. FSS and Reflectarrays are particularly the hottest domains of RF design. But due to their large electrical size and complex cellular patterns, full-wave analysis of these structures require enormous amount of memory and processing requirements. Therefore conventional techniques based on linear meshing either fail to simulate such structures or require resources not available to a common antenna designer. An indigenous technique called Scale-changing Technique addresses this problem by partitioning the cellular array geometry in numerous nested domains defined at different scale-levels in the array plane. Multi-modal networks, called Scale-changing Networks (SCN), are then computed to model the electromagnetic interaction between any two successive partitions by Method of Moments based integral equation technique. The cascade of these networks allows the computation of the equivalent surface impedance matrix of the complete array which in turn can be utilized to compute far-field scattering patterns. Since the computation of scale-changing networks is mutually independent, execution times can be reduced significantly by using multiple processing units. Moreover any single change in the cellular geometry would require the recalculation of only two SCNs and not the entire structure. This feature makes the SCT a very powerful design and optimization tool. Full-wave analysis of both uniform and nonuniform planar structures has successfully been performed under horn antenna excitation in reasonable amount of time employing normal PC resources.

MSc Thesis:

Pre-processing and Ultra Compressed Parametric Modelling of UWB Antenna Measurements

Abstract: Complex UWB antenna design procedures have always been seen as a hindrance to the rapid growth of UWB applications. Various methodologies to simply this process have been sought over the past few years. One such domain of growing interest is “UWB Antenna Modelling”. The research in this field will not only provide a simple and concise representation of cumbersome antenna measurement data but also promises ultimately, to significantly simply UWB antenna realization techniques. The need for concise and efficient antenna models for UWB communications has been widely addressed in the past years. Yet, areas of statistical modelling for antennas lie vastly unexplored. On the other hand, statistical modelling for UWB channel is well in its mature state. Various UWB applications e.g. Body area networks (BANs) and WLANs require antenna models to include the effects due to proximity environment in which they are being used. This concept further refines to defining a class of antennas which behave similarly in similar conditions and therefore can be represented by a general model representative of the entire “antenna class”. This stochastic model can be easily interfaced with the existing stochastic models of UWB channel and therefore make the design of a UWB system simpler. This thesis addresses this topic through an approach based on a drastic reduction of the descriptive parameters set of antennas based on double projection of their Transfer Function or Impulse Response. This compression is achieved through a parametric modelling based on the Singular Expansion Method (SEM) and the Spherical Modes Expansion Method (SMEM). Extremely high data compression rates can be obtained “with losses” (i.e. to some extend at the expense of accuracy). It is also possible to achieve very high data compression rates with a good precision. The method is applied to various prototypes, focusing as a first step on small or moderate size antennas. It is shown in practice that data compression rates as high as 99.9% are achievable.
