This paper discusses some of the major experimental features of microwave nonlinearity in
high temperature superconductors, both intrinsic and extrinsic. The case is made for solving
the problem of extrinsic nonlinearity through the use of localized measurements of microwave
surface impedance and electromagnetic fields. Along these lines, a brief introduction is given
to our work on scanning near-field microwave microscopy.
KEY WORDS: High temperature superconductors; microwave nonlinearity.
