This document provides guidelines and describes how to easily port S60 2nd Edition
C++ applications to S60 3rd Edition. The document has been written based on
experiences of porting regular S60 2nd Edition applications, such as the S60 Platform:
POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from
the example are shown in Chapter 8, “Application build changes,” and in Appendix A,
“Code example." In addition, Appendix B, "Commonly used functions that require
capabilities," and Appendix C, "Commonly used interfaces that have been changed or
removed," provide useful information on some frequently used functions and interfaces
in third-party applications.

We analyze, both analytically and numerically, the effectiveness
of cloaking an infinite cylinder from observations by electromagnetic
waves in three dimensions. We show that, as truncated approximations
of the ideal permittivity and permeability tensors tend towards
the singular ideal cloaking fields, so that the anisotropy ratio tends to
infinity, the D and B fields blow up near the cloaking surface. Since
the metamaterials used to implement cloaking are based on effective
medium theory, the resulting large variation in D and B will pose a
challenge to the suitability of the field averaged characterization of "
and 碌. We also consider cloaking with and without the SHS (softand-
hard surface) lining, shown in [6] to be theoretically necessary
for cloaking in the cylindrical geometry. We demonstrate numerically
that cloaking is significantly improved by the SHS lining, with both
the far field of the scattered wave significantly reduced and the blow
up of D and B prevented.

Electrostatic discharge (ESD) phenomena have been known to mankind since Thales of
Miletus in approximately 600 B.C.E. noticed the attraction of strands of hay to amber.
Two thousand six hundred years have passed and the quest to obtain a better under-
standing of electrostatics and ESD phenomenon continues. Today, the manufacturing
of microelectronics has continued the interest in the field of electrostatic phenomenon
spanning factory issues, tooling, materials, and the microelectronic industry
