It is the same everywhere and in all directions.
A dielectric whose polarization always has a direction that is parallel to the applied electric field, and a magnitude which does not depend on the direction of the electric field. I have unfortunately no example to give you. But some plastics do have properties close to being isotropic dielectric.
isotropic dielectric: permittivity is a scalar
anisotropic dielectric: permittivity is a tensor
homogeneous dielectric: permittivity is independent of position
non-homogeneous dielectric: permittivity is dependent on position
Bakelite is optically isotropic.

It is an alloy, very probable not homogeneous.
NO

the universe is isotropic & homogeneous, meaning there is no center. the observable universe has a center, which is the part of the universe we can see. we are at the center of the observable universe.

For elastic, isotropic and homogeneous materials, zero Poisson's ratio means that the material doesn't present lateral deformation on bending, compressing or extending.
Bakelite is optically isotropic.
Aluminium and steel are e.g. of isotropic materials.
The meaning of isotropic is with identical properties independent on the direction.
The velocity of s-wave is 60% of p-wave, for a given homogeneous and isotropic medium and a fixed time p-wave would travel farther.
No
Concrete is an isotropic material with different strength properties with respect to the type of imposed loadings.
An omnidirectional antenna can be practically implemented but an isotropic antenna cannot be implemented practically. An isotropic antenna resembles an ideal antenna with ideal values for all parameters.
