Abstract
Field enhancement of applied electric field is the foundation for the
variety of applied domains at a nanoscale level. Traditionally,
efforts to achieve field enhancement have required the use of
complicated metamaterial-based structures with a transition behavior.
Here, the electromagnetic field solution of the TM-polarized wave that
interacts with an optical-axis-driven hyperbolic medium with a
transition behavior is established. Detailed calculations reveal that
such field enhancement can be achieved over a broad range of incident
angles (i.e., near critical angle). Definitely, such flexibility of
the incident angle for achieving the field enhancement enriches the
understanding and provides novel prospective toward its practical
realization.
