Description: 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.

Description: The gauss, abbreviated as G or Gs, is the cgs unit of measurement of a magnetic field B, which is also known as the magnetic flux density or the magnetic induction . It is named after German mathematician and physicist Carl Friedrich Gauss. One gauss is defined as one maxwell per square centimeter. The cgs system has been formally superseded by the SI system, which uses the tesla (T) as the unit for B. One gauss equals 1×10− 4 tesla (100 μT) (1 T = 10000 G).-The gauss, abbreviated as G or Gs, is the cgs unit of measurement of a magnetic field B, which is also known as the magnetic flux density or the magnetic induction .

The file "manager.f" is the highest level of control, co-ordinating, so to speak, the sequence to calls to to solvers, initializations, etc. The module solver_mod.f90 contains the solver routines. The module util_mod.f90 contains functions called upon to do various i/o
To compile the codes into an executable, type: "make"
