Wireless Power Transfer Presentation

Question 1

What are the two types of short range wireless power transmission technologies and how do they transfer energy?

Answer 1

• Capacitive Power Transfer (CPT): Alternating Electric Field
  
  • Inductive Coupling: Alternating magnetic field

Question 2

What are the benefits/deficits of the different long distance wireless transfer methods?

Answer 2

Microwaves:
