UVC sanitation system and IoT campus systems
During the COVID-19 crisis, designed a timer-based, transportable UVC light system for the sanitation of hospital rooms.
As part of a smart/green campus initiative, developed in-house IoT kits aimed at reducing electricity consumption.
Coordinated the implementation of an on-campus smart car parking system.
Cube Sat
Designing a CubeSat for “KLU Satellite Mission” for scientific measurements in space environment.
Payloads: RF reflectometer based on GNSS signal/ electron density measurements.
Satellite & Deep Space Communications (2009–2019)
Research focused on Ka, Q/V band and Free-Space Optical (FSO) satellite communications, atmospheric propagation modeling, radar system design, and inter-satellite links for Earth observation and planetary missions.
Space Communications & Atmospheric Propagations
Investigated atmospheric effects for satellite missions utilizing Ka and Q/V bands, as well as Free-Space Optical (FSO) communication wavelengths.
Cloud & Precipitation Analysis: Analyzed the vertical profile of drop size distribution and cloud attenuation effects on millimeter-wave signals.
Rainfall Rate Modeling: Developed a 'Rain Rate Intensity Model' for satellite communications in the Indian region, using data from Automatic Weather Stations, rain gauges, and satellite beacons (Ka/ Q/V bands).
Multiband Analysis: Comprehensive link budget analysis for Ka, Ku, and Q/V bands.
Free-Space Optical communication (FSO): Investigated the feasibility of FSO communications for high-bandwidth space-to-ground and inter-satellite links.
Site Diversity Implementation: Identification of ideal gateway locations across the Indian region for LEO/MEO/GEO satellite missions using site diversity to mitigate atmospheric fading.
Link Availability Studies: Research into "Adaptive Power Control" for tropical climates, achieving 40% reduction in antenna size while maintaining high availability during monsoon periods.
Radar Systems & Payload Development
Phased Array Radar Design: Development and analysis of phased array systems for satellite missions.
Scientific Payload Development: Designing payloads for Earth observation and planetary studies at Ka/Q/V and FSO wavelengths.
Space Debris Tracking: Prototype design of a Ka/Q/V band radar system specifically for tracking space debris.
RF Hardware Innovation: Designed and installed a Ka-band beacon measuring station at KL University.
National-Scale Validation & Mapping
Meteorological Network Audit: Conducted a comprehensive reliability validation of Automatic Weather Stations (AWS) across India.
Climatological Mapping: Developed Rain Contour Maps for the Indian region to assist in communication link design.
System Noise Analysis: Bright Band temperature analysis and its correlation with system noise temperature.
The objective is to establish communications or transfer information using the sun's wavelength (solar spectrum). I have developed the initial concept and am currently exploring the technical options for designing and building a prototype for experimentation. I would welcome the opportunity to discuss the technical analysis and feasibility of this concept further.
Design of Norton Amplifiers for Multicouplers: This project aims to replace FET-based stages with Norton amplifiers to achieve a noise figure (NF) of less than 3 dB. This approach mitigates issues with inconsistent FET quality while maintaining high linearity, specifically preserving IP2 and IP3 intermodulation suppression at required levels. Several prototypes were successfully designed and tested.
