Yes.

Displacement current is proportional to the rate of change of the
electric field. It moves at right angles to the direction of
propagstion.

Like charges repel without electrical conduction so a capacitor passes
ac while blocking dc.

A standing wave antenna stores energy in the magnetic field near its
center during one half of the cycle and in the electric fields near its
ends during the other half cycle.

Dielectric displacement is the electrical strain which occurs in a
dielectric medium when an electric field is applied. It is analogous to
the magnetic flux density and is expressed in charge per unit area or
coulombs per aquare meter.

J.C. Maxwell speculated displacement current produces magnetic lines of
force same as conduction current does, therefore an alternating magnetic
field would produce an alternating electric field and so on ad
infinitum. This was the key to electromagnetic radiation. Hertz later
proved Maxwell correct in the laboratory.

Now why did I expect such an answer from you? The Physics World states
that displacement current does not exist
with respect to radiation and you hang on to outdated books and sneer
at modern day advances
Seems like you will never ever accept change
