No the fields do not jump. The normal of the D-field and tangential components of the E field are continuous across the boundary of the cylinder

Also the cylinder is infinitely long

Th E-field is in the x-direction and the cylinder's axis is alligned along the z-axis. Therefore the E-field is normal to the cylinder. There is no tangential component to the E-field. The field is static everywhere, i.e. not propagating.

I am having trouble with a homework problem assigned by my physics professor. An infinitely long cylinder of radius a and relative dielectric constant Er is immersed in a static electric field E=Eox where x is supposed to denote a unit vector in the x direction. The cylinder is alligned on the...
