Flares are between the most energetic transient phenomena in the Sun. Nowadays the consensus is that magnetic?reconnection processes are in the origin of these events, when a sudden energy release produces radiation, charge acceleration and plasma heating. At radio? frequencies above a few GHz gyrosynchrotron is the main emission mechanism during flares. That emission depends on two sets of parameters: those vinculated to suprathermal electron population (energy distribution, density, etc), and the parameters related to ambient plasma (magnetic field, density, temperature, etc). First codes for gyrosynchrotron emission only took into account homogeneous sources, that appropriately model small sources with moderate anisotropy. In this work we present calculations of the gyrosynchrotron emission due to inhomogeneous sources.
