Abstract: This paper presents a coupled-wave analysis of triangular-lattice photonic crystal surface emitting lasers (PCSELs) with transverse magnetic polarization. Six plane waves coupled by Bragg ...

Abstract: A millimeter-wave bandpass filter for Ka-band applications is proposed, which uses a rectangular waveguide and spoof surface plasmon polariton (SSPP) with a notched band. This filter ...

We further analyze the low-frequency content of the Hussar data using surface waves - because of their significant coherent low-frequency energy. The multichannel analysis of surface waves (MASW) ...

Both beginners and experts will be able to surf, with waves ranging from 20cm to 2 metres. There will also be lessons and group activities able to be booked on-site, as well as a spa and gym.

Dramatic footage has captured the moment a North Staffordshire village was left under water. And the scenes earlier this morning even show waves lapping up against businesses in Forsbrook.
