Lecture #1 1/3: Coordinates, Maxwell and radiation

ANTENNAS AND PROPAGATION lecture 1: coordinates, Maxwell and radiation 1. Quantities in physics: measurement units, scalars and vectors. 2. Dot (scalar) and cross (vector) products of two vectors, directions and signs. 3. Coordinate systems: 3D, rectangular, right-handed. 4. Cartesian coordinate system, measurement units. 5. Unit (base) vectors in the cartesian coordinate system. 6. Dot (scalar) and cross (vector) products from vector components. 7. Calculating the distance in cartesian and arbitrary coordinate system. 8. Spherical coordinate system, measurement units, unit (base) vectors. 9. Example: calculating the distance along a meridian. 10. Example: calculating the distance along a parallel. 11. Lame coefficients (scale factors) in arbitrary curvilinear/spherical coordinates. 12. Rotating the spherical coordinate system.
