ABSTRACT: Context
and Background: The product of the electromagnetic (EM) wave’s
power P times its period τ, i.e. Pτ, is the amount of energy conserved
in EM wave’s absorption in matter. Whether Pτ is the amount of energy conserved in the emission of EM waves from matter is
not assessed. Motivation: In this research,
we perform a computational study to explore the ability of Pτ to represent the
amount of energy conserved in EM wave’s emission from matter. Hypothesis: Since the magnitude of the power P of
emitted EM waves computed through Larmor’s formula for a rotating dipole is
excessively small, we alternatively hypothesize that Pτ and the law of conservation of energy can lead to a realistic
estimation of P. Methods: We
estimate the power PAME of
the anomalous microwave emission (AME), a well-characterized radiation
generated in the interstellar medium (ISM) by spinning dust grains, and one possible source of contamination of the cosmic
microwave background (CMB). For our estimation of PAME, we assume the AME to be generated in a molecular
cloud mostly populated by spinning silicate nanoparticles (SSNs) or polycyclic
aromatic hydrocarbon (PAH) spinning dust grains. Indeed, SSNs and PAHs are
listed among the most probable sources of AME, and their characteristics are
well-known. We discriminate between realistic and non-realistic values of PAME based upon the magnitude
of two parameters that depend on PAME:
the significant distance z, and the
time of photon production T. The
parameter z is the space interval from the spinning dust grain within which the
spinning dust grain’s electric field is effective. Results: Using the
information available for AME, SSNs and PAHs, we estimate the power PAME using both Larmor’s
formula and Pτ. We compare and
comment the results obtained for z and T. Conclusions: Our study
highlights the effectiveness of Pτ over
Larmor’s formula in providing a realistic value of PAME. This finding might have consequences in quantum
technology of single photon detection and production.
