โœฆ Synopsis

An effective Lagrangian calculation of pion photoproduction including all nucleon resonances up to fi = 1.7 GeV is presented. We compare our results with recent calculations and show the influence of different width parametrizations and off-shell cutoffs on the photoproduction multipoles. We determine the electromagnetic couplings of the resonances from a new fit to the multipole data.

## Abstract Electromagnetically coupled notch filters is a relatively recent innovation. Resonators with three ring geometries (square, triangular, and circular) and L (half wave) are fabricated (all 2.4 GHz) on TMM4 (ฮต~r~ = 4.5, h = 0.762 mm) substrates (without ground plane) and coupled electroma
