  We propose the use of networks of standard, commercially-available coaxial
cables as a platform to realize photonic lattice models. As a specific example,
we consider a brick wall lattice formed from coaxial cables and T-shaped
connectors. We calculate the dispersion of photonic Bloch waves in the lattice:
we find a repeated family of three bands, which include a flat band and two
Dirac points. We then demonstrate a method to displace the Dirac points,
leading to an induced artificial gauge field, and a method to energetically
isolate the flat band. Our results readily suggest that the interplay of
nonlinearities and non-trivial topology are a natural avenue to explore in
order to unlock the full power of this proposed platform.
