Query: Duality-symmetric axion electrodynamics and haloscopes of various
  geometries   Within the dual symmetric point of view, the theory for seeking axion dark
matter via haloscope experiments is derived by exactly solving the dual
symmetric axion electrodynamics equation. Notwithstanding that the conventional
theory of axion electrodynamics presented in [Phys. Rev. Lett. 51, 1415 (1983)
and J. Phys. A: Math. Gen. 19, L33 (1986)] is more commonly used in haloscope
theory, we show that the dual symmetric axion electrodynamics has more
advantages to apply into haloscope theory. First, the dual symmetric and
conventional perspectives of axion electrodynamics coincide under
long-wavelength approximation. Moreover, dual symmetric theory can obtain an
exact analytical expression of the axion-induced electromagnetic field for any
states of axion. This solution has been used in conventional theory for
long-wavelength approximation. The difference between two theories can occur in
directional axion detection or electric sensing haloscopes. For illustrative
purposes, we consider the various type of resonant cavities: cylindrical
solenoid, spherical solenoid, two-parallel-sheet cavity, toroidal solenoid with
a rectangular cross-section, and with a circular cross-section. The resonance
of the axion-induced signal, as well as the ratio of the energy difference over
the stored energy inside the cavity, are investigated in these types of
cavities.
