Unformatted text preview: ECSE 351 Electromagnetic Fields McGill University ECE Dept. - Prof. Milica Popovi Lecture 1: Vector Analysis Objective: learn an important tool No detailed mathematical proofs PLEASE pay attention to this chapter and make certain that you are comfortable with all the concepts even if much of it may seem familiar. Drill problems given throughout the text highly recommended! ? Vector Scalar ? magnitude magnitude & direction Can you think of some examples? McGill ECE ECSE 351 Electromagnetic Fields Prof. M. Popovic ? Vector Scalar ? magnitude magnitude & direction Can you think of some examples? McGill ECE ECSE 351 Electromagnetic Fields Prof. M. Popovic Scalar and vector FIELDS What is a field? A function that connects origin with some point in space (temperature in bowl of soup) Always related to a region (bowl) Some quantity is defined at EVERY point of the region (e.g. temperature and temperature gradient ) McGill ECE ECSE 351 Electromagnetic Fields Prof. M. Popovic NOTATION do not forget to note if a quantity is a vector! In book boldface When we write McGill ECE ECSE 351 Electromagnetic Fields Prof. M.
