A fingerprint recognizing system is built with two
principal components: the fingerprint administrator and
the fingerprint recognizer. Fingerprints are identified by
their special features such as ridge endings, ridge
bifurcation, short ridges, and ridge enclosures, which are
collectively called the minutiae.
ASK function, this is a block that has three input and one output. the input are the two carrier that have different amplitute, and the digital signal representing the information or data to be modulated.
A cylindrical wave expansion method is developed to obtain the scattering field for an ideal
two-dimensional cylindrical invisibility cloak. A near-ideal model of the invisibility cloak is set up
to solve the boundary problem at the inner boundary of the cloak shell. We confirm that a cloak
with the ideal material parameters is a perfect invisibility cloak by systematically studying the
change of the scattering coefficients from the near-ideal case to the ideal one. However, due to the
slow convergence of the zeroth order scattering coefficients, a tiny perturbation on the cloak would
induce a noticeable field scattering and penetration.
This is the procedure for lab 1. This is a two-week lab. Prelab should be done BEFORE going to the lab session. In this lab the dielectric properties of materials and how these properties affect electric fields will be analized.
