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 ...
This circuit is a nice edge detector that gives you
synchronous notification of edges on your input signal. There s no excuse for not doing this it s a tiny
circuit in just five lines of Verilog.
