My name is Rohit Sammeta and I am a professional engineer trained in Electromagnetics.
I am currently (since Aug 2010) pursuing my PhD at the University of Colorado, Boulder working on Frequency Independent (FI) antennas. We are developing a low-profile sinuous antenna that operates from 500MHz to 2.5GHz with very little variance in its far-field and VSWR characteristics. The frequency independent nature is preserved using dielectric loading and an absorber-less cavity. The antenna is also being designed to be capable of withstanding high powers (200 W CW).
Before starting my PhD, I worked as an Application Engineer for EMSS USA Inc. (Dec 2006 to July 2010). My job was to apply the EM simulation software FEKO to various areas where the analysis of fields generated by electric or magnetic current sources is required. I also provided technical support for customers in the use of FEKO, executed short courses and represented the company in academic conferences and trade shows.
Before this job, I was busy getting my Masters degree (Thesis: Substrate Integrated Waveguide Slot Array Antennas and their Numerical Analysis) in Electromagnetics from the University of Mississippi, Oxford (Aug 2004 - May 2007). I designed, built and measured a substrate integrated waveguide slot array antenna at 10GHz. I also wrote a Methods of Moments code to analyze the problem of slots in an infinite substrate problem more efficiently than commercial software.
I have a Bachelor of Technology degree in Electrical Engineering from the Indian Institute of Technology, (IIT) Bombay (July 2000 - July 2004).
