Any open source 2D Planar EM Solvers? (SONNET alternative)

[kurtulmehtap]

Are there any open source 2D Planar EM Solvers? (SONNET alternative)
I just want simulate 2D structures like Microstrip filters.
BTW, I tried emGine, the GUI is not as useful as SONNET and the core is not open source.
Than you All...

Some Free EM Simulation tools

1.MEEP

Meep (or MEEP) is a free finite-difference time-domain (FDTD) simulation software package developed at MIT to model electromagnetic systems, along with our MPB eigenmode package
# Simulation in 1d, 2d, 3d, and cylindrical coordinates.
# Distributed memory parallelism on any system supporting the MPI standard. Portable to any Unix-like system (GNU/Linux is fine).
# Arbitrary anisotropic electric permittivity ε and magnetic permeability μ, along with dispersive ε(ω) and μ(ω) (including loss/gain) and nonlinear (Kerr & Pockels) dielectric and magnetic materials, and electric/magnetic conductivities σ.
# PML absorbing boundaries and/or perfect conductor and/or Bloch-periodic boundary conditions.
# Exploitation of symmetries to reduce the computation size — even/odd mirror symmetries and 90°/180° rotations.
# Complete scriptability — either via a Scheme scripting front-end (as in libctl and MPB), or callable as a C++ library; a Python interface is also available.
# Field output in the HDF5 standard scientific data format, supported by many visualization tools.
# Arbitrary material and source distributions.
# Field analyses including flux spectra, frequency extraction, and energy integrals; completely programmable.
# Multi-parameter optimization, root-finding, integration, etcetera

Meep looks fine but has no GUI, its based on ftdt .
It is said Method of Moments (MOM) is better suited for 2D. ANy MOM codes...

MEEP is good, I used it ..but its extremely slow and unconfortable since it has no GIU.

Anything with a GUI?
