Selvan, SSN College of Engineering, Chennai. This talk will cover the electromagnetic properties of dielectrics. The physical principles underlying the idea of dielectric constant will be discussed. Elementary ideas of the so called artificial dielectrics will also be considered. Day 1, Afternoon Revisiting some important EM concepts Dr. S. V. Kulkarni, IIT Bombay The talk will briefly cover various important concepts from electrostatics to Maxwell's equations. Some of the subtle points, not explained or emphasized adequately in many text books on the subject, will be discussed. It is essential to understand distinction between low frequency and high frequency electromagnetic phenomena and ways to analyze them. While using commercial software for computing fields, understanding of scalar and vector magnetic potentials is an important prerequisite. The talk will end with highlighting of current research trends in computational electromagnetics. Day 2, Morning (1) Integral equation methods in electromagnetics (2) Frequency dependence of dielectric constant by Dr. Uday Khankhoje, Indian Institute of Technology, Delhi. Talk 1 - Integral equations are powerful mathematical techniques that are indispensable to modern electromagnetic simulations, whether used for computing radar cross-sections of aircraft, or in the design of highspeed microwave circuits. In this lecture, starting with some basic concepts in vector calculus, I will demonstrate a few building blocks for integral equations. As an illustration, we will derive Huygen's principle and discuss its physical meaning. Talk 2 - We all know that light spreads into various colours as it passes through a prism, and that this is because the prism bends each colour slightly differently. In this lecture, I will derive the physics of this phenomenon by using a simple ball-spring model of an electron bound to a molecule under the influence of an applied electric field. Day 2, Afternoon Art of electrodynamics by Dr. Debatosh Guha, Electronics & Electrical Communication Engg., IIT Kharagpur This talk will address an unconventional approach of understanding the Electromagnetic fields and theory; and will look at the problem of Maxwellian Electrodynamics from a different angle. This will follow a 'track' which is entirely different from that we knew from our school days to post-graduate level. Day 3, Morning Fundamentals of periodic structures in electromagnetics by Dr. K.J. Vinoy, IISc, Bangalore. Metamaterials have caught the attention of electromagnetics researchers for their exciting applications in microwave and optical frequencies due to their seemingly unique properties. Although the theoretical possibility of existence of such periodic media was proposed several decades ago, experimental validations for these came out, only recently. Transmission line equivalents of such media have brought up several new possibilities for the design of radio frequency components and circuits. Some of these have demonstrated right-handed and lefthanded propagation characteristics above or below a specified frequency. Frequency selective surfaces, high impedance surfaces, and electromagnetic bandgap materials are just a few other periodic geometries that have caught the attention at different points of time. This talk will give a general overview of theoretical fundamentals as well as our research directions on these topics. Day 3, Afternoon Understanding antennas on finite ground planes by Dr. Harishankar Ramachandran, IIT, Madras. Many modern applications of antennas have them mounted on finite bodies, for instance, automobile antennas, radiating structures on aeroplanes and space antennas. The radiation patterns of such antennas are quite different from the traditional antenna, especially when the wavelength of the radiated signal is comparable to the size of the object on which the antenna is mounted. In this talk we will review the traditional antenna, and look at why antennas with finite ground planes have different properties and how they can be analysed and simulated.
