The talks delivered J. Soto during the session of the working group of electromagnetic corrections to hadronic processes at the Eight International Symposium MENU99, cover a wide range of problems. In particular, those include: construction of the effective Lagrangians that then are used for the evaluation of electromagnetic corrections to the decays of K mesons; evaluation of some of the low-e...

To investigate the effect of forest spatial structure on SAR interferometry (InSAR) data requires an electromagnetic scattering model capable of expressing radar observation in terms of parameters describing forest spatial structure. In this paper, we propose an electromagnetic scattering model for mixed-species forest which includes the coherent effect of forest structure and preserves phase i...

Received Jan 29, 2017 Revised Jun 10, 2017 Accepted Aug 11, 2017 This paper presents an analytic solution to the scattering properties of chiral elliptic cylinder embedded in infinite chiral medium due to incident plane wave. The external electromagnetic fields as well as the internal electromagnetic fields are written in terms Mathieu functions and expansion coefficients. In order to obtain bo...

We investigate the low-energy behavior of the four-point Green's function ? describing virtual Compton scattering oo the nucleon. Using Lorentz invariance, gauge invariance, and crossing symmetry, we derive the leading terms of an expansion of the operator in the four-momenta q and q 0 of the initial and nal photon, respectively. The model-independent result is expressed in terms of the electro...
