This book provides results of analysis of typical solar events statistical analysis the
diagnostics of energetic electrons and magnetic field as well as the global behavior of solar
flaring loops such as their contraction and expansion. It pays particular attention to
analyzing solar flare loops with microwave hard X-ray optical and EUV emissions as well as
the theories of their radiation and electron acceleration transport. The results concerning
influence of the pitch-angle anisotropy of non-thermal electrons on their microwave and hard
X-ray emissions new spectral behaviors in X-ray and microwave bands and results related to
the contraction of flaring loops are widely discussed in the literature of solar physics. The
book is useful for graduate students and researchers in solar and space physics.
