Similar to how stealth materials were developed to reduce the radar wave energy returning from an aircraft, here we explore a low-cost laboratory demonstration that uses similar principles to prevent detection of an object by an ultrasonic sensor. This demonstration setup can be used as a starting point to encourage students to explore the surface…

The present paper deals with the issue of Electrical Engineering, particularly its impact and standard of education in India from its initiation till present date. We have explored the transition of Electrical Engineering from disciplines of science to a discipline of engineering and technology. A comprehensive study of Electrical Engineering…
