Abstract63% of the world's population is connected via the internet as of 2022. What about the remaining 37% which is about 3 billion people!? Why are they not connected yet? The traditional commercial viable approaches either lack capacity or lack reach. Newer technological approaches are needed to create economically sustainable ways to connect all. Also, it is no longer that only people need connectivity but with a plethora of intelligent devices coming into existence machines requiring connectivity are also growing in an exponential way. 5G puts the step in the right direction towards this gap in connectivity but is far from completely addressing it. At Astrome, we have developed and are developing different products and solutions to address the diverse market needs towards bridging this gap. This talk will elaborate the gap and mechanisms to address them and provide a view of the journey at Astrome in this direction.

AbstractNASA’s Jet Propulsion Laboratory, which completed eighty years of its existence in 2016, builds spacecraft and instruments for NASA missions. Exploring the universe and our own planet Earth from the space has been the mission of NASA. Robotics missions such as Voyager, which continues to go beyond our solar system, missions to Mars and other planets, exploring the stars and galaxies for astrophysics missions, exploring and answering the question, “are we alone in this universe?” has been the driving force for NASA exploration since its inception. Fundamental science questions drive the selection of NASA missions. We develop new technologies and innovative instruments to make measurements that can answer these science questions. In this presentation, we will present an overview of the state-of-the-art radar, spectrometers, radiometers, and other instruments that we are currently developing and layout the details of the science questions they will try to answer. Rapid progress in multiple fronts, such as commercial software for component and device modeling, low-loss circuits and interconnect technologies, cell phone technologies, and submicron scale lithographic techniques are making it possible for us to design and develop smart, low-power yet very powerful instruments that can even fit in a SmallSat or CubeSat. We will also discuss the challenges of the future generation instruments in addressing the needs for critical scientific applications. The research described herein was carried out at the Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California, USA, under contract with National Aeronautics and Space Administration.

AbstractMicrowaves are electromagnetic radiation in the frequency range of 300MHz to 300GHz corresponding to wavelengths of 1m down to 1 mm. They can be used in many applications such as - communication, imaging visually obscured objects, wifi and cooking. In this presentation, we will start with a kitchen oven with a magnetron source at ~ 2.4 GHz and demonstrate how electronics can bel upset and even damaged. We will then move on to high-power (100’s MW to GW) microwave sources and illustrate how they can be weaponized against electronic systems. Individual drones and swarms of drones are already being used in warfare with data links in microwave frequencies to controllers on ground. Some illustrative examples of sources and antennas will also be presented.

AbstractDiagnosing and early detection of chronic diseases in remote settings is always a challenge without access to costly, well-equipped clinical laboratories and trained medical personnel. Consequently, developing diagnostics for chronic conditions that are cost effective and can be easily implemented, remains an important goal in global health. To achieve this goal, one promising approach is to detect disease biomarkers from accessible body fluids with point-ofcare (POC) biosensors that are inexpensive, minimally invasive and do not require trained medical personnel. Point-of-care biosensor systems can potentially improve patient care through real-time and remote health monitoring. Apart from infectious conditions, global health challenges have shifted towards noncommunicable chronic diseases (NCDs) such as diabetes mellitus, heart disease, chronic kidney disease, liver disease and cancer, which constitute an increasing majority of global mortality. PathShodh Healthcare is driven by a social mission to achieve the goal of affordable, accurate and cost-effective diagnostics, based on the patented bio-sensing technologies. Here, I will discuss the PathShodh journey to develop the novel products for point of care diagnostics of public health conditions

AbstractOptical fluorescence is fast emerging as a possible substitute for nuclear medicine isotopes in functional biomedical imaging. We will give a brief overview of fluorescence based optical and photoacoustic tomography. Static settings correspond to the imaged quantity of interest such as the absorption/scattering coefficient of a pathological tissue, not varying with time. In dynamic settings, such as those found in pharmacokinetic imaging, the time varying concentrations of injected fluorophores are spatio-temporally imaged, along with their underlying (pharmacokinetic) rates of leakage with respect to the tissue under investigation.
We will introduce (a) an enhanced model for directional sources and scattering with a delta-Eddington based simplified spherical harmonics approximation, in fluorescence optical tomography, and, (b) a fluorescence photoacoustic tomographic framework for the dynamic pharmacokinetic tomography problem.
