Maximum Gain, Effective Area, and Directivity [PDF]
IEEE Transactions on Antennas and Propagation, 2018 Fundamental bounds on antenna gain are found via convex optimization of the current density in a prescribed region. Various constraints are considered, including self-resonance and only partial control of the current distribution.

Effective area of photonic crystal fibers [PDF]
Optics Express, 2002 We consider the effective area A_eff of photonic crystal fibers (PCFs) with a triangular air-hole lattice in the cladding. It is first of all an important quantity in the context of non-linearities, but it also has connections to leakage loss, macro-bending loss, and numerical aperture.

Analytical Formulas for Dispersion and Effective Area in Hollow-Core Tube Lattice Fibers
Fibers, 2021 In this work, we propose analytical formulas for the estimation of dispersion properties and effective area of the fundamental mode of hollow-core inhibited coupling fibers with a microstructured cladding composed by a ring of dielectric tubes.
