THE CONFERENCE

About the ELS Conference

The 20th Electromagnetic and Light Scattering Conference (ELS-XX) will be held in Hotel “Bahía Tropical” located in Almuñecar, one of the most popular tourist destinations on the Costa Tropical of Granada, Spain. The conference will build on the remarkable success of the previous ELS conferences held in Amsterdam, Helsinki (twice), New York, Vigo, Halifax, Gainesville, Bremen, Salobreña, St. Petersburg, Bodrum, Hatfield, Taormina, Lille, Leipzig, College Park, College Station, Hangzhou, and the 19th conference held online on July 2021.

The main goal of the ELS conference series is to bring together scientists and engineers studying various aspects of light scattering and to provide a relaxed academic atmosphere for in-depth discussions of theoretical advances, measurements, and applications.

JQSRT special issue

Following the highly successful ELS practice, we will be soliciting papers for the ELS-XX Topical Issue of the Journal of Quantitative Spetroscopy and Radiative Transfer (JQSRT) and hope that you will want your state-of-the-art research to become part of yet another benchmark collection of papers on electromagnetic scattering and its applications. This Topical Issue will consist only of full-size papers documenting research either reported at the conference or pertaining to the main topics of ELS-XIX. Extended abstracts of conference presentations will not be considered. Each submission will be thoroughly reviewed by at least two independent referees to ensure that all accepted manuscripts satisfy the highest standards of scientific quality adopted for JQSRT.

VENUE

Venue

The Meeting will take place at "Hotel Bahía Tropical", Paseo del Tesorillo, s/n, 18690 Almuñécar, Granada.

All participants are invited to stay at the Bahía Tropical Hotel. The cost of the room (double or single) is €85 (taxes and breakfast included). You can book your room through the registration form.

How to get Almuñécar?

By Car: Getting to Almuñécar by car is simple and presents no difficulty, the city is perfectly communicated; if you come from Madrid, you must take the Andalusia Highway (A-4) and in Bailén connect with the Sierra Nevada-Costa Tropical Highway (A-44), later you must join the A-7; If you are traveling from Malaga or Almería: your reference road will be the Autovía del Mediterráneo (A-7), a highway parallel to the coastal road, the Carretera Nacional N-340.

The two roads meet again at the entrance to La Herradura, exit 305 West (if you are coming from Malaga) and at the entrance to Almuñécar, taking exit 314 East (if you are coming from Granada or Almería).

By Bus: To get to Almuñécar and La Herradura by bus, you have buses from the main cities such as Granada, Malaga, Seville, Madrid..., visit the ALSA company website and find the timetable that best suits you. These buses leave daily and during the summer season the frequency is increased.

By Plane: You must take a flight from your destination to the Malaga-Costa del Sol airport or to the Granada-Jaén airport and then use any type of ground transportation.

From Malaga airport: If you plan to come by plane, learn about and choose the transport alternatives to get to Almuñécar from Malaga “Costa del Sol” airport (80 km from Almuñécar).
From Granada airport: Get to know and choose the transport alternatives to get to Almuñécar from Granada-Jaén “Federico García Lorca” Airport (90km from Almuñécar).
