Failed to Improve

Actual situation

\phi \approx 6^{\circ}
ϕ≈6∘\phi \approx 6^{\circ}

Conditions for Improvement

  • The pattern is thin
     
  • When we have larger theta
     
  • This will have a close form condition

Future work

  • Derive the condition for improvement and how
     
  • Consider more complicated shape of pattern
     
  • Consider more physical effects

A pattern of complicated shape
