In questo lavoro si studia la teoria lineare dell’elettromagnetismo nella ionosfera, caratterizzata da un’equazione costitutiva che associa la presenza di effetti di memoria all’azione attuale del campo elettrico. Dopo aver trattato le restrizioni termodinamiche all’equazione costitutiva prescelta, si dimostra l’esistenza di un dominio di dipendenza. Infine, si determina il comportamento asintotico delle soluzioni, nonché esistenza ed unicità delle stesse.
Abstract
We consider the linear theory of the Electromagnetism in the ionosphere characterized by a constitutive equation which associates the presence of memory effects with the actual action of the electric field. After studying the thermodynamic restrictions on the assumed constitutive equations, a domain of dependence inequality is derived. Then, asymptotic behaviour of solutions is studied together with uniqueness and existence theorems.
