Classical microwave imaging poses an inverse scattering problem where several microwave transmitters illuminates an object and scattered fields in numerous receiver location are measured. When energy in the microwave, UHF region propagates through a biological body, its phase velocity and absorption coefficient are function of the complex permittivity of the medium. This in turn is a function of tissue type and functional state of the tissue. The high value of dielectric constants of water allows a measure of tissue discrimination on the basis of water content. Therefore, measurement of...

Never ever in the annals of human civilization, the importance of ecological resilience has become so important and imperative as we are perceiving now. Both the need and greed of food economics have driven the resource bases of our ecosystem, to a dilapidated and fragile status. By 2050 the world's population will touch close to 9.5 billion and we have to scale up our food production 60% more over what it is right now. In India by 2040, we have to cross 450 million tonnes of our targeted food production to keep rhythm with population growth. By 2035 we are going to cross the population of...
