Space and time cavities with internally trapped electromagnetic fields
are considered as wave-particle models of extended time-like and spac
e-like particles. It is shown that in an N-dimensional (N = 1, 2, 3) s
pace-cavity photons undergo a conversion into a system composed of a b
radyon at rest and N infinite-speed transcendent tachyons moving circu
larly about the bradyonic constituent. The time-like Klein-Gordon equa
tion and its space-like counterpart for inner and outer fields associa
ted with trapped radiation have been derived.
