Thanks. The real word frequency is 10 Hz and a is 1mm.
I will try the version you sent.

Subject: Re: [Meep-discuss] Very novice user: error message help
Hi Noel,
I'm also relatively new to MEEP, and some of the error codes can be quite
cryptic till you've seen them before. To me, the clue in your is list-ref,
so I went carefully through your lists commenting different things out to
see if I could isolate the error. Although this can be lengthy if you
really can't spot something it is a useful way of debugging. In your case
there are two syntax errors:
1. the make is not required when using a predifined material (i.e
perfect-electric-conductor)
2. Be careful with the syntax of the source
Below is a corrected version that at least starts, your frequency however
does seem very small, but this may be what you intend.
